Temperature Conversion Formulas

Celsius to Fahrenheit

°F = (°C × 9/5) + 32

Example: 25°C = (25 × 9/5) + 32 = 77°F

Fahrenheit to Celsius

°C = (°F - 32) × 5/9

Example: 98.6°F = (98.6 - 32) × 5/9 = 37°C

Celsius to Kelvin

K = °C + 273.15

Example: 0°C = 0 + 273.15 = 273.15 K

Kelvin to Celsius

°C = K - 273.15

Example: 300 K = 300 - 273.15 = 26.85°C

Fahrenheit to Kelvin

K = (°F - 32) × 5/9 + 273.15

Example: 32°F = (32 - 32) × 5/9 + 273.15 = 273.15 K

Kelvin to Fahrenheit

°F = (K - 273.15) × 9/5 + 32

Example: 373.15 K = (373.15 - 273.15) × 9/5 + 32 = 212°F

Frequently Asked Questions

How to convert Celsius to Fahrenheit?

Multiply the Celsius temperature by 9/5 (or 1.8) and add 32. Formula: °F = °C × 9/5 + 32

What is the difference between Celsius and Kelvin?

Kelvin is an absolute temperature scale starting at absolute zero. To convert: K = °C + 273.15. The difference is always 273.15 degrees.

Why does the US use Fahrenheit?

The US adopted Fahrenheit before the metric system became standard. Most other countries use Celsius, which is part of the metric system.
