The formula
°F = °C × 1.8 + 32
Worked through with a real value: 25 degrees Celsius = 77 degrees Fahrenheit.
Going the other way: °C = °F × 0.555556 − 17.7778, so 1 degree Fahrenheit = -17.2222 degrees Celsius.
What each unit is
- degree Celsius °C
- Zero at the freezing point of water and 100 at its boiling point, at standard pressure. The everyday scale almost everywhere outside the United States.
- degree Fahrenheit °F
- Water freezes at 32 and boils at 212. Used for weather and cooking in the United States and a few of its neighbours.
