Overview
Convert between Celsius (°C), Fahrenheit (°F), and Kelvin (K). Useful for weather, cooking, scientific experiments, and any context where temperature unit conversion is needed.
Formula
°F = °C × 9/5 + 32 °C = (°F − 32) × 5/9 K = °C + 273.15 °C = K − 273.15 °F = K × 9/5 − 459.67
How to Use

Tips
- ✔Freezing point of water: 0°C = 32°F = 273.15 K
- ✔Boiling point of water: 100°C = 212°F = 373.15 K
- ✔Normal body temperature 36.5°C is about 97.7°F.
- ✔Kelvin does not use the degree (°) symbol.
- ✔Absolute zero is 0 K = −273.15°C = −459.67°F.
FAQ
Q. At what temperature are Celsius and Fahrenheit equal?
Celsius and Fahrenheit are equal at −40 degrees: −40°C = −40°F.
Q. When is the Kelvin scale used?
Kelvin (K) is the SI base unit for thermodynamic temperature and is widely used in scientific research and engineering. It starts from absolute zero (0 K), so there are no negative values.
Q. Why does the US use Fahrenheit?
The US adopted the Fahrenheit scale historically (proposed by Daniel Gabriel Fahrenheit) and continues to use it in everyday life. Scientific fields in the US also use Celsius and Kelvin.
