Frequently Asked Questions about the Temperature Converter

How do I convert Celsius to Fahrenheit?
Multiply by 9/5 and add 32. So 20 °C = (20 x 9/5) + 32 = 68 °F.
How do I convert Fahrenheit to Celsius?
Subtract 32, then multiply by 5/9. So 100 °F = (100 - 32) x 5/9 = 37.8 °C.
What is Kelvin?
An absolute temperature scale where 0 K = -273.15 °C = absolute zero. Used in science. Kelvin is the same size as a Celsius degree, just offset by 273.15.
What is room temperature?
Around 20-22 °C (68-72 °F), the comfortable range for most people indoors.
What temperature is freezing?
Water freezes at 0 °C / 32 °F / 273.15 K under standard atmospheric pressure.
What temperature is boiling?
Water boils at 100 °C / 212 °F / 373.15 K at standard atmospheric pressure. At higher altitudes water boils at lower temperatures.
