Common Temperature Conversion Formulas

Here are some common conversion formulas for temperature units that you might find useful:

Celsius to Fahrenheit
(celsius × 9/5) + 32 = fahrenheit

Multiply the temperature value in Celsius by 9/5, then add 32 to get Fahrenheit. Water freezes at 0°C (32°F) and boils at 100°C (212°F).

Fahrenheit to Celsius
(fahrenheit - 32) × 5/9 = celsius

Subtract 32 from the temperature value in Fahrenheit, then multiply by 5/9 to get Celsius. The two scales meet at -40 degrees.

Celsius to Kelvin
celsius + 273.15 = kelvin

Add 273.15 to the temperature value in Celsius to get Kelvin. Kelvin is the SI base unit of temperature with 0K being absolute zero.

Kelvin to Celsius
kelvin - 273.15 = celsius

Subtract 273.15 from the temperature value in Kelvin to get Celsius. This conversion is commonly used in scientific calculations.
