Common temperature formulas
Temperature conversion depends on both scale offset and scale size, so it is not just multiplication.
- Fahrenheit = Celsius x 9 / 5 + 32
- Celsius = (Fahrenheit - 32) x 5 / 9
- Kelvin = Celsius + 273.15

How to use the temperature converter
1
Enter the temperature you want to convert, such as a forecast, oven setting, thermostat number, lab value, or device reading.
2
Choose the source scale you already have, then switch the target scale to Celsius, Fahrenheit, or Kelvin.
3
Use the result to understand weather, follow a recipe, check a setting, or compare a temperature range in another scale.
Example conversions
0 °C
32 °F
Water freezes at 0 °C, which is 32 °F in the Fahrenheit scale.
100 °C
212 °F
A useful reference point for boiling water at standard atmospheric pressure.
180 °C oven setting
356 °F
Common when adapting a metric recipe for a Fahrenheit oven, often rounded to 350°F or 360°F.
When to double-check
- Recipes, weather, and thermostat settings are usually fine with rounded values.
- Scientific or engineering work may require exact precision and context such as pressure.
- Kelvin values should not be negative in normal physical temperature contexts.
Helpful when temperature scales do not match the task
Useful for weather, recipes, and settings
Read a forecast, oven temperature, thermostat setting, or science value in the scale you actually need.
Compare nearby temperatures in place
Change the number or scale and keep the converted result visible while checking a range.
Works across common temperature scales
Use it for Celsius, Fahrenheit, and Kelvin in forecasts, cooking, classroom work, and device settings.
Useful while traveling, cooking, or checking gear
Convert a temperature beside a forecast, recipe, thermostat, appliance, or lab note.
