Temperature Units & Calculator

Absolute temperature requires both a scale factor and an offset: K = °C + 273.15; K = (°F + 459.67) × 5/9. Do not use this conversion for a temperature difference.

Detailed explanation & worked examples

Conversion method

Base value = input × source factor + source offset. Output = (base value − target offset) ÷ target factor. Only units from this family can be converted together.

Worked example

For the first two units below: 1 Kelvin (K) becomes -272.15000000 Celsius (°C).
