Frequently Asked Questions

What is the formula for Celsius to Fahrenheit?

°F = (°C × 9/5) + 32. For example, 100°C = (100 × 9/5) + 32 = 212°F (boiling point of water).

What is Kelvin?

Kelvin is the SI unit of temperature. 0K (absolute zero) is the lowest possible temperature. To convert: K = °C + 273.15. Water freezes at 273.15K and boils at 373.15K.

What is Rankine?

Rankine is an absolute temperature scale like Kelvin but based on Fahrenheit. 0°R = absolute zero. To convert: °R = (°F + 459.67). It is primarily used in engineering calculations.
