About Fahrenheit and Celsius
The Fahrenheit temperature range is called for German physicist Daniel Gabriel Fahrenheit and is the measurement of temperature generally used by the United says (and its associated territories) and also by several nations in the Caribbean. Top top the Fahrenheit scale, water freezes in ~ 32°F and also boils in ~ 212°F (at sea level).
The Celsius temperature scale—originally called centigrade and later renamed for sweden astronomer Anders Celsius—is used practically everywhere rather in the world. Top top the Celsius scale, water freezes in ~ 0°C and also boils at 100°C (at sea level).
