Convert between Celsius, Fahrenheit, and Kelvin instantly. Get accurate temperature conversions with detailed formulas and real-world examples.
Celsius is used worldwide for everyday temperature measurements. It's based on the freezing (0°C) and boiling (100°C) points of water at sea level. Used in science and most countries except the USA.
Fahrenheit is primarily used in the United States for everyday temperature measurements. It's based on a brine solution freezing at 0°F and human body temperature at 96°F (later adjusted to 98.6°F).
Kelvin is the SI unit for thermodynamic temperature. It starts at absolute zero (0 K), the point where all molecular motion ceases. Used in scientific and engineering applications. No degree symbol is used with Kelvin.
