Fahrenheit Celsius Kelvin Rankine Reaumur

Reference

Everyday benchmarks 32 F = 0 C freezing; 212 F = 100 C boiling at sea level

Science and engineering Kelvin starts at absolute zero; Rankine is the Fahrenheit-based absolute scale

Quick formulas C = (F - 32) x 5/9; F = C x 9/5 + 32

Tool Introduction

Use this temperature converter for weather, cooking, HVAC settings, lab notes, engineering references, and international travel. It converts between Fahrenheit, Celsius, Kelvin, Rankine, and Reaumur.

Fahrenheit is still common for U.S. weather and thermostats, Celsius is standard in most of the world, and Kelvin is the practical choice for science because it starts at absolute zero.
