How to Convert Temperature Units
Temperature conversion is essential in everyday life, cooking, science, and travel. The most common conversion is between Celsius (°C), used in most countries worldwide, and Fahrenheit (°F), used mainly in the United States. To convert Celsius to Fahrenheit, multiply by 9/5 (or 1.8) and add 32. To convert Fahrenheit to Celsius, subtract 32 and multiply by 5/9. Kelvin (K) is the SI unit for thermodynamic temperature, used in science and engineering. It starts at absolute zero (0 K = −273.15 °C). Rankine is the imperial equivalent of Kelvin.
