As you most likely know, water is an extremely heavy. That doesn’t take long for it to add up to something the is incredibly hard to move around. This is particularly true for large drums of water.

You are watching: How much does a 55 gal drum of water weigh

A 55-gallon drum of water weighs around 458.7 lbs or 208.06 kg.To figure this out, you multiply the load of one us liquid gallon (8.34 pounds or 3.78 kilograms) through the volume of the north (55 gallons.)

Do note, however, that the answers may vary according to number of factors. I’ll cover all the bases by mentioning the differences below.

What Factors affect the load of a 55-Gallon drum of Water?

The gallon measurement, water type, and water temperature affect the weight of a 55-gallon drum of water. The drum material will likewise have an impact on the overall weight (e.g., plastic weighs much less than steel).

Technically, heaviness plays a role in the calculations too. The weight of a 55-gallon drum of water will be various on earth contrasted to the moon or the planet Jupiter!

Gallon Measurements


The example over uses a united state liquid gallon (US gal), i m sorry is regularly used in weighing the water and also other liquids.

That said, the answer above is applicable if girlfriend live in the Americas. But if you live in various other countries, you might come increase with one more solution. That’s since other countries use various other gallon measurements, such together the imperial gallon.

US fluid Gallon

As mentioned, the united state gal is what’s provided to measure up liquids in the Americas. The US embraced this measurement native the old wine/Queen anne gallon, adhering to its self-reliance from an excellent Britain.

For each united state gal, you acquire 231 cubic inches or 3.78 liters of liquids. Given these numbers, the united state liquid gallon is 16.6% lighter 보다 the royal gallon. 

US dried Gallon

A dry gallon is same to ⅛ the the dry measure of the united state Winchester bushel. This bushel measures 2150.42 cubic inches or 35.23 liters. 

Therefore, a us dry gallon actions 268.80 cubic inch or 4.40 liters.

As through the liquid gallon, the UK gallon is the united state adaptation of an old UK measurement (Winchester or corn gallon.)

True come its name, the dry gallon is provided to measure up ‘dry’ assets such as berries, apples, or grapes.

Imperial Gallon

In the UK and most commonwealth countries, the imperial gallon (imp gal) measure is used. It has a volume of 277.5 cubic inches or 4.54 liters.

Before the introduction of the royal gallon, the UK used various gallon measurements.

One example is the ale gallon, which sweet 4.62 liters or 282 cubic inches. As the name suggests, it was offered to measure beer throughout the power of Queen Elizabeth I.

The Winchester or corn gallon, top top the various other hand, weighed 268 cubic inch or 4.40 liters. This kind of measure up was offered in the late 15th century under the reign of King Henry VII.

The Queen anne or alcohol gallon is smaller, measuring only 231 cubic customs or 3.78 liters. Its usage started method back in the 14th century. However, Queen anne made the a statute in 1707 – therefore the name.

Type that Water

You might put various types of water in your drum, including freshwater and saltwater.


A kind of water with low salt contents – less than 1% concentration. It comes from the water vapor precipitation (rain, snow, or mist.)

This fluid is often discovered in ponds, lakes, streams, and also rivers, representing much less than 0.01% the the water on the earth’s surface. Many freshwater – 1.75 to 2% – is locked in ice, snow, or glaciers. Around 0.5 to 0.75% is preserved in soil moisture.


Saltwater is created when freshwater moves within the land. The circulation erodes the rocks and their minerals, which room then channeled to the oceans and estuaries.

Despite that is name, saltwater content is not minimal to sodium chloride (table salt.) It likewise contains various other salts and also minerals, particles that make saltwater denser/heavier than freshwater. Saltwater constitutes many of the water on the planet at 97%.

How lot Does 1 Gallon that Water Weigh?

At the temperature of 62 °F or 17 °C, the weight of one united state gallon of new water is 8.34 lbs or 3.78 kg. This load may change according to temperature. Name is water will be lighter, and also colder liquids will be heavier.

How lot Does Saltwater weigh per Gallon?

Each gallon the saltwater weighs around 8.5 lbs or 3.85 kg, compared to freshwater, i beg your pardon is just 8.34 lbs or 3.78 kg.This is due to the fact that saltwater is denser, which makes it heavier 보다 freshwater.

Considering this measurements, a 55-gallon drum of saltwater will certainly be more heavier at 467.5 lb or 211.75 kg.

The included weight is attributed to the salt and also minerals, which take it 3.6% the the water’s weight. Because that every gallon that saltwater, you’ll get around 0.28 lb or 0.13 kg that salt and also other particles.

Next, we will certainly talk around how temperature affects water.


When you heat water, you boost its energy. The molecules end up colliding, producing much more space between each other. This results in reduced water density.

Cold water, on the various other hand, is denser due to the procedure of hydrogen bonding.

In easier terms, hot water is lighter 보다 cold water. This is why as soon as you swim in a swimming pool or the ocean, the hot water is near the surface, if the colder water is deeper. 

In one article, the author did a small experiment by to compare the weight of warm water and cold water. 

The results show what researchers expect: a pint of warm water only weighed 1.16 lbs or 0.53 kg. A pint of cold water, ~ above the various other hand, was heavier at 1.23 lbs or 0.56 kg.

That’s why once you boil a gallon the water to 200 °F (or 93.33 °C), it will only weigh 8.04 lbs or 3.64 kg.

Ice: Less thick Than Water

As mentioned, temperature affect the weight of water. Cold water is ‘heavier’ than hot water, so the former remains at the bottom that the latter.

Despite this setup, water that viewpoints freezing temperature – aka ice cream – is always less thick than hot or cold water. The best example that this is the iceberg you check out floating on the water. Once water freezes, its thickness decreases by 9% because it experience structural changes.

In liquids, molecules are spread out far. But in ice, the molecule arrange in a lattice formation, therefore making the material much less dense.

Taking this formation into account, a gallon of ice would only weigh 7.59 lb or 3.44 kg. The said, a 55-gallon drum of ice would certainly be lighter at only 417.45 lb or 189.2 kg.

‘Heavy’ Water

So around the ice the sinks top top the bottom of your water glass?

According to the us Geological Survey, the something that speaks because that itself: heavy ice. It’s made with hefty water, i m sorry is 10.6% denser 보다 the typical freshwater.

Heavy water or D2O develops when hydrogen atom are replaced with deuterium, a hydrogen isotope that includes only one neutron and one proton.

Heavy water is frequently used together a ghost moderator in strength plants. In laboratories, the is provided as an isotopic tracer.

As the surname alludes, hefty water is, the course, heavier than freshwater. Each gallon weighs about 9.22 lb or 4.18 kg, therefore a 55-gallon of heavy water weighs around 507.1 lb or 229.9 kg.


Weight is the force exerted by gravity on one object’s mass. In various other words, it synchronizes to the stamin of gravitational traction on the object.

Gravities differ according come planets. The planet has a heaviness of 9.8 m/s2. The moon’s heaviness is only 1.62 m/s2, if Jupiter has a whopping heaviness of 24.79 m/s2.

Because of these variations, a 55-gallon north of water will certainly be lighter ~ above the moon. And, together expected, it will certainly be more heavier on Jupiter.

According come the Exploratorium website, the adhering to are the dimensions of a 55 us gal of fresh water—on other planets:

Moon: based on the moon’s heaviness (as mentioned above,) the weight of a 55-US gal that freshwater here is 76.1 lb or 34.51 kg.Mercury: The heaviness of the very first planet is 3.7 m/s2, thus making the 55-gallon water weigh 173.3 lb or 78.60 kg.Venus: The water here weighs 416 lb or 188.69 kg. Due to the fact that the gravity on this planet is just 8.87 m/s2.Mars: although Mars is in which method the earth twin, the gravity right here is just 3.71 m/s2. This makes for a 55-gallon water weight of 172.9 lb or 78.42 kg.Jupiter: top top the biggest planet in the solar system, a 55-gallon the water will certainly weigh 1159.5 lb or 525.94 kg.Saturn: The ringed planet has actually a gravity of 10.44 m/s2. Together such, a 55-gallon drum of water here weighs 488 lb or 221.35 kg.Uranus: The planet’s heaviness is slightly weaker compared to that of the earth at just 8.69 m/s2. Together a result, a 55-gallon the water below will weigh just 407.7 lb or 184.92 kg.Neptune: Gravity in Neptune is much more robust at 11.15 m/s2. Thus, water weighs heavier right here at 516 lb or 234.05 kg.Pluto: as the furthest planet, Pluto only has actually a heaviness of 0.62 m/s2. Here, water is the lightest at just 30.7 lb or 13.92 kg.

While you might not be measuring water on an additional planet soon, it’s advantageous to know just how gravity affects weight measurements.

Type the Drum


Although the weight of water is the primary problem here, many civilization tend come forget around the weight of the north itself.

A stole drum will certainly weigh 48 lbs or 22 kg. A plastic one weighs lighter at 25 lb or 11 kg.

Considering this, a steel north containing 55 gallons of water will weigh 506.7 lbs or 230 kg.

As because that 55 gallons that water in a plastic drum, the weight will be 483.7 lbs or 219 kg.

Steel and plastic are only two of the numerous materials used to do 55-gallon drums. Other species include:

Fiber drum. This drum, i beg your pardon is do of fiberboard, has a removable plastic or stole cover. It weighs approximately 17 lbs or 7.7 kg.Red plastic drum (open or closed). The shade red is molded ~ above the plastic chin so it i will not ~ rust or peel. This type of drum weighs about 22 lbs or 10 kg.Nestable plastic drum. This comes through tapered wall surfaces to aid reduce the an are it occupies. Nestable drums weigh about 24 lbs or 10.8 kg.Lined steel drum, open top. The lining stays clear of contamination, so girlfriend don’t need to disinfect the north after use. Since it’s lined v steel, the can obtain as heavy as 45 lbs or 20 kg.Stainless steel drum, open up top. This type of north is well-known for the tensile strength and resistance come corrosion. That is the most heavy drum obtainable since that weighs 50 lbs or 23 kg.

Similar to what was done above, all you must do is add the drum’s load to the load of 55 gallons that water (458.7 lbs or 208.06 kg). By doing so, friend will acquire the full weight of the water – and the drum you’re using.

Final Thoughts

A 55-US gal drum of freshwater weighs 458.7 lbs or 208.06 kg. This is no a solved measurement, though, because several factors can influence the weight. They incorporate the unit of measure, form of water, and temperature.

The load may likewise vary follow to the kind of north (e.g., steel vs. Plastic.)

That said, it’s vital to consider all these determinants to get an exact measurement that a 55-gallon drum of water.
