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

1. 1Enter the temperature value to convert.
2. 2Select the source temperature unit (°C, °F, or K).
3. 3Select the target temperature unit.
4. 4View the converted result.

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.
