Temperature Converter
Convert between Fahrenheit, Celsius, and Kelvin.
Type a temperature, pick units, get the conversion. Shows all three scales side by side so you can see the equivalent in every system at once.
Examples: 32F = 0C = 273.15K (water freezes). 100C = 212F = 373.15K (water boils at sea level). 98.6F = 37C (human body temp).
The three scales
Fahrenheit is used primarily in the United States. Water freezes at 32 F and boils at 212 F (at sea level). Celsius is used in most of the rest of the world. Water freezes at 0 C and boils at 100 C. Kelvin is the scientific standard, used in physics and chemistry. It starts at absolute zero (the coldest possible temperature) and uses the same degree size as Celsius. 0 K equals -273.15 C.
The conversion formulas
- F to C: (F - 32) * 5/9
- C to F: C * 9/5 + 32
- C to K: C + 273.15
- K to C: K - 273.15
Common reference points
- Water freezes: 32 F = 0 C = 273.15 K
- Room temperature: ~68-72 F = ~20-22 C
- Human body: 98.6 F = 37 C
- Water boils (sea level): 212 F = 100 C = 373.15 K
- Oven (medium): 350 F = 177 C
