What this tool does

Converts temperature between Celsius, Fahrenheit, Kelvin, and Rankine scales with explicit mathematical conversion steps and physical reference points.

How to use this tool

Enter a temperature value.
Select the source scale (°C, °F, K, or °R).
Select the target scale to see step-by-step arithmetic and equivalent values across all scales.

Temperature Formulas

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

Unlike length and weight, temperature scales do not share a common zero point (except thermodynamic Absolute Zero at 0 K / -273.15 °C / -459.67 °F).
