K = °C + 273.15

°C = K - 273.15

Detailed Temperature Conversion Formulas

Celsius ↔ Fahrenheit

°F = (°C × 9/5) + 32

Example: 20°C = (20 × 9/5) + 32 = 68°F

°C = (°F - 32) × 5/9

Example: 68°F = (68 - 32) × 5/9 = 20°C

Celsius ↔ Kelvin

K = °C + 273.15

Example: 0°C = 0 + 273.15 = 273.15K

°C = K - 273.15

Example: 273.15K = 273.15 - 273.15 = 0°C

Fahrenheit ↔ Kelvin

K = (°F - 32) × 5/9 + 273.15

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

°F = (K - 273.15) × 9/5 + 32

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