Celsius to Fahrenheit Converter
How to convert Celsius to Fahrenheit
°F = °C × 1.8 + 32
To convert Celsius to Fahrenheit, multiply the value in Celsius by 1.8, then add 32.
1 °C = 33.8 °F
Examples
- Normal body temperature: 37 °C × 1.8 + 32 = 98.6 °F
- Water boils at sea level: 100 °C × 1.8 + 32 = 212 °F
Good to know
The exact relationship is °F = °C × 1.8 + 32. Doubling the Celsius value and adding 30 gives a rough Fahrenheit estimate that is close at everyday temperatures, and the two scales read the same at −40.

Unit definitions
- Celsius (°C)
- The Celsius scale is defined as the temperature in kelvins minus 273.15, which puts the freezing point of water at about 0 °C and its boiling point at about 100 °C at sea-level pressure. It is the everyday temperature scale in most of the world.
- Fahrenheit (°F)
- On the Fahrenheit scale water freezes at 32 °F and boils at 212 °F at sea-level pressure, 180 degrees apart. It is the everyday temperature scale in the United States.
