Celsius (°C)
The Celsius scale sets the freezing point of water at 0° and the boiling point at 100° at standard atmospheric pressure.
Celsius is the everyday temperature scale in most countries, on weather forecasts, and in science alongside kelvin.

How to convert
Exact offset formulas in both directions, plus a worked example.
°F = °C × 9/5 + 32
°C = (°F − 32) × 5/9
Multiply Celsius by 9/5, then add 32 to get Fahrenheit.
Subtract 32 from Fahrenheit, then multiply by 5/9 to get Celsius.
Example: convert 37 °C to °F
37 °C → 98.6 °F (celsius to fahrenheit)
