Temperature Converter
The one non-linear scale - handled with offsets.
Enter a value above to convert between °C and °F.
How to convert temperature
Temperature is the one non-linear scale here: each scale has a different zero, so you add or subtract an offset as well as scaling. The core formulas are °F = °C × 9/5 + 32, °C = (°F − 32) × 5/9, and K = °C + 273.15. Rankine relates to Fahrenheit the way Kelvin relates to Celsius: °R = °F + 459.67.
Worked example
To convert 100 °C to Fahrenheit: 100 × 9/5 + 32 = 212 °F. To convert normal body temperature, 98.6 °F, to Celsius: (98.6 − 32) × 5/9 = 37 °C.
When you'll use a temperature converter
Temperature conversion is everyday for weather (Celsius versus Fahrenheit), cooking and oven settings, travel between metric and US regions, and science or engineering work in Kelvin. Because the scales have different zeros, 0 in one is never 0 in another - which is exactly why a converter helps.
