Temperature Converter

Convert Celsius, Fahrenheit, and Kelvin instantly.

A temperature converter is an everyday essential for cooks following international recipes, travelers adapting to local weather reports, scientists working with thermodynamic data, and students studying physics or chemistry.

This free online temperature converter lets you switch between Celsius (C), Fahrenheit (F), and Kelvin (K), the three most universally used temperature scales, with instant and accurate results. All conversions route through Celsius as the intermediate step to prevent compounded rounding errors.

Just type in any field and the other two update automatically. No button to press.

: This tool converts between Celsius (C), Fahrenheit (F), and Kelvin (K), the three most widely used temperature scales.
: All conversions go through Celsius as the intermediate step: the input is converted to C first, then from C to the target scale. This prevents compounded rounding errors.
: Absolute zero, the coldest theoretically possible temperature, is 273.15 C, 459.67 F, and exactly 0 K.
