Fahrenheit is used primarily in the United States, while Celsius is used in most other countries and in scientific contexts. Kelvin is the SI base unit for temperature and is used extensively in physics and chemistry. Water freezes at 32°F / 0°C / 273.15K and boils at 212°F / 100°C / 373.15K at standard atmospheric pressure.
Subtract 32 from the Fahrenheit value, then multiply by 5/9. For example, 72°F = (72 - 32) × 5/9 = 22.22°C. A quick estimate: subtract 30 and divide by 2.
Multiply the Celsius value by 9/5, then add 32. For example, 25°C = (25 × 9/5) + 32 = 77°F. A quick estimate: double the value and add 30.
Absolute zero is 0 Kelvin, which equals -273.15°C or -459.67°F. It is the theoretical lowest possible temperature where all molecular motion stops. Nothing can be cooled below this temperature.
