Enter a temperature and choose the scales to convert between.
Converted temperature
How the Temperature Converter works
Temperature scales have different zero points, so conversion uses formulas instead of a single factor.
°F = °C × 9/5 + 32 · °C = (°F − 32) × 5/9 · K = °C + 273.15
Step-by-step calculation
- 1Enter the temperature.
- 2Choose the scales.
- 3Apply the conversion formula (not a single factor).
Worked example
98.6 °F = 37 °C = 310.15 K. Water freezes at 0 °C (32 °F) and boils at 100 °C (212 °F) at sea level.
