Enter a temperature in Celsius to convert it to Fahrenheit or Kelvin.
Why temperature is special
Temperature conversion is trickier than length or weight because the scales do not share a zero. Celsius sets zero at the freezing point of water; Fahrenheit puts that same point at 32. So converting needs both a multiply and an add, not a single factor.
The everyday anchors are worth memorizing: water freezes at 0 Celsius or 32 Fahrenheit, body temperature is about 37 Celsius or 98.6 Fahrenheit, and water boils at 100 Celsius or 212 Fahrenheit. The tool also handles Kelvin, the scientific scale that starts at absolute zero.
The formula
Worked example
100 degrees Celsius equals 212 degrees Fahrenheit, the boiling point of water.
How to read your result
Temperature scales do not share a zero point, so conversion needs both a multiply and an add, unlike length or weight. The tool also supports Kelvin.
Frequently asked questions
- What is 0 Celsius in Fahrenheit?
- 32 degrees Fahrenheit, the freezing point of water.
- What is body temperature?
- About 37 Celsius, which is 98.6 Fahrenheit.
- Why is temperature different from other conversions?
- Because the scales have different zero points, not just different sizes.
