How to Use This Calculator

Enter your Temperature (e.g. 100), From — choose from , , , and To — choose from , , . Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Unit conversion uses a fixed conversion factor between the two units. Multiply the input value by the factor to get the result. For temperature, the formula depends on the scales (e.g., °C to °F: multiply by 9/5 and add 32).

Worked Example

The weather forecast says it is 35°C outside. You want to know what that is in Fahrenheit. Using the formula °F = + 32, 35°C converts to 95°F. This converter handles Celsius, Fahrenheit, and Kelvin instantly.

Understanding Your Result

Key temperature reference points: Absolute zero 0 K / −273.15°C / −459.67°F. Water freezes at 0°C / 32°F / 273.15 K. Water boils at 100°C / 212°F / 373.15 K at 1 atm (sea level). Human body temperature 37°C / 98.6°F. Oven baking range: 150–230°C / 300–450°F. Kelvin is always used in thermodynamic equations — never negative. Temperature differences in Celsius and Kelvin are equal: a 10°C rise = a 10 K rise.
