All-in-One Temperature Converter
Convert between all temperature units at once
Temperature Converter
Metric standard (water freezes at 0°)
US standard (water freezes at 32°)
Scientific (starts at absolute zero)
Conversion Formulas
Celsius ↔ Fahrenheit
°F = (°C × 9/5) + 32°C = (°F - 32) × 5/9Celsius ↔ Kelvin
K = °C + 273.15°C = K - 273.15Fahrenheit ↔ Kelvin
K = (°F - 32) × 5/9 + 273.15°F = (K - 273.15) × 9/5 + 32Quick Reference

About Temperature Scales
This all-in-one temperature converter lets you instantly convert between the three most common temperature scales: Celsius, Fahrenheit, and Kelvin. Simply enter a value in any field, and the other two will update automatically.
Celsius (°C)
The metric scale used worldwide for weather, cooking, and everyday measurements. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure.
Fahrenheit (°F)
Primarily used in the United States for weather and cooking. Water freezes at 32°F and boils at 212°F at standard atmospheric pressure.
Kelvin (K)
The SI unit for scientific measurements. Starts at absolute zero (the coldest possible temperature). Used extensively in physics, chemistry, and engineering.
Common Use Cases
- Converting weather temperatures when traveling internationally
- Adjusting cooking and baking temperatures from recipes
- Understanding body temperature readings in different scales
- Scientific calculations and experiments
- Setting thermostat and HVAC temperatures
