Temperature Converter

Convert four temperature scales with affine formulas. Unlike most unit conversions, temperature scales require both multiplication and an offset.

Reference conversions

Source unit	Equivalent
Celsius to Fahrenheit	°F = °C × 9/5 + 32
Fahrenheit to Celsius	°C = (°F − 32) × 5/9
Celsius to Kelvin	K = °C + 273.15
Celsius to Rankine	°R = (°C + 273.15) × 9/5

Worked example

25 °C = 77 °F = 298.15 K = 536.67 °R.

Important interpretation

A temperature difference is not converted the same way as an absolute temperature. For example, a 1 °C interval equals a 1.8 °F interval without adding 32.

Usage boundaries and result checks

Temperature Converter is for this task: Convert Celsius, Fahrenheit, Kelvin, and Rankine with correct offset formulas. It runs in the browser; start with a short, non-sensitive sample and confirm the behavior before processing more data.

Best use

Use it for a focused Temperature Converter task when a quick browser workbench is appropriate.
