Celsius to Fahrenheit

Multiply the Celsius temperature by 9/5 (or 1.8) and add 32. Formula: °F = (°C × 1.8) + 32.

Multiply 20 by 1.8 (36) and add 32. 20°C is equal to 68°F.

Yes, Celsius (formerly known as centigrade) is the metric system's temperature unit, named after astronomer Anders Celsius.

Simply add 273.15 to the Celsius temperature (e.g. 0°C = 273.15 K).

A degree Celsius represents a larger change in temperature than a degree Fahrenheit; specifically, 1°C is equal to 1.8°F.
