Temperature Formulas
°F = °C x 9/5 + 32
°C = (°F - 32) x 5/9
K = °C + 273.15

Frequently Asked Questions
Multiply by 9/5 (or 1.8) then add 32. Example: 25°C = 25 x 1.8 + 32 = 77°F. Quick approximation: double the Celsius value and add 30.
Absolute zero (0 Kelvin = -273.15°C = -459.67°F) is the lowest possible temperature — the point at which all molecular motion stops. It is theoretically impossible to reach exactly.
