Convert 72°F to Celsius or 20°C to Fahrenheit.
Convert temperature between Fahrenheit, Celsius and Kelvin. It is designed for quick estimates and everyday problem solving. When a calculation affects a contract, tax filing, medical decision or other high-stakes situation, verify the result with the appropriate professional or authoritative source.
68°F equals (68 − 32) × 5/9 = 20°C. To convert Celsius to Kelvin, add 273.15; therefore 20°C is 293.15 K.
Important distinction: Fahrenheit-to-Celsius is not a simple multiplication because the scales have different zero points. Values below absolute zero (−273.15°C, −459.67°F, or 0 K) are not physically valid temperatures.
Convert temperature between Fahrenheit, Celsius and Kelvin.
Celsius is used as the intermediate scale: °F = °C × 9/5 + 32 and K = °C + 273.15.
