About These Units
Celsius (°C)
Celsius (°C), also called centigrade, is the metric temperature scale used by most countries worldwide. Water freezes at 0°C and boils at 100°C at standard pressure. To convert Celsius to Fahrenheit: °F = (°C × 9/5) + 32. Normal body temperature is 37°C. Named after Swedish astronomer Anders Celsius.
Kelvin (K)
Kelvin (K) is the SI base unit for temperature, used in science and engineering. Absolute zero (0 K) is -273.15°C or -459.67°F—the coldest possible temperature where molecular motion stops. No degree symbol is used with Kelvin. Water freezes at 273.15 K. Named after Lord Kelvin.
