Conversion formulas

• °F = (°C ÁE9/5) + 32
• °C = (°F ∁E32) ÁE5/9
• K = °C + 273.15
• °C = K ∁E273.15

Common reference points

• Water freezes: 0°C / 32°F / 273.15 K
• Water boils: 100°C / 212°F / 373.15 K
• Body temperature: ~37°C / 98.6°F / 310.15 K
• Absolute zero: ∁E73.15°C / ∁E59.67°F / 0 K

FAQ

Which countries use Fahrenheit?

The United States, its territories (Puerto Rico, Guam), and a few other countries use Fahrenheit for everyday temperature. Most of the world uses Celsius.

Can temperature go below 0 Kelvin?

No. Absolute zero (0 K) is the theoretical minimum temperature. It is physically impossible to go below it as it represents the complete absence of thermal energy.

At what temperature are Celsius and Fahrenheit equal?

They are equal at ∁E0°. Both ∁E0°C and ∁E0°F represent the same temperature.
