Common Temperature Conversion Formulas
Here are some common conversion formulas for temperature units that you might find useful:
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).
Subtract 32 from the temperature value in Fahrenheit, then multiply by 5/9 to get Celsius. The two scales meet at -40 degrees.
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.
