How to Convert Temperature Units
To perform a conversion, look up the target unit's conversion factor relative to the base unit (kelvin). Below are the exact mathematical formulas for the most common temperature unit pairs:
Celsius to Fahrenheit
°F = (°C × 9/5) + 32 Fahrenheit to Celsius
°C = (°F - 32) × 5/9 Celsius to Kelvin
K = °C + 273.15 Kelvin to Celsius
°C = K - 273.15 Temperature Unit Conversion Charts
