Temperature Converter

A temperature converter translates measurements of heat between different scales, such as Celsius, Fahrenheit, and Kelvin.

Absolute zero is the lowest limit of the thermodynamic temperature scale, equivalent to 0 Kelvin, -273.15°C, or -459.67°F.

Multiply the Celsius temperature by 9/5 and add 32. For example, 0°C is equal to 32°F.

Subtract 32 from the Fahrenheit temperature and multiply by 5/9. For example, 100°F is equal to 37.78°C.

Add 273.15 to the Celsius temperature. For example, 100°C is equal to 373.15 Kelvin.

Kelvin is the primary unit of temperature in the physical sciences, useful because it starts at absolute zero, meaning it contains no negative values.

Because they have different starting points (zero points). Water freezes at 0°C but 32°F, and a degree of Celsius is 1.8 times larger than a degree of Fahrenheit.

Yes, all calculation logic runs locally in your browser. No temperature values are transmitted to our servers.

Yes, the tool converts Kelvins directly to Fahrenheit using the formula: °F = (K - 273.15) × 1.8 + 32.

The calculations maintain high floating-point precision, displaying up to 10 decimal places for scientific accuracy.
