Temperature Converter
Convert temperatures between Celsius, Fahrenheit and Kelvin instantly.
How to use the Temperature Converter
- Enter the temperature value.
- Select the source unit (°C, °F, or K).
- Select the target unit.
- Click Calculate.
Formula
°F = °C × 9/5 + 32
°C = (°F − 32) × 5/9
K = °C + 273.15
Example
100°C to °F: 100 × 9/5 + 32 = 212°F.
Step-by-step calculation
- Multiply by 9/5: 100 × 1.8 = 180.
- Add 32: 180 + 32 = 212.
- Result: 212°F.
Real-world uses
- International weather comparison.
- Cooking recipe conversions.
- Scientific temperature readings.
Common mistakes
- Mixing up the formulas for C→F vs F→C.
- Forgetting the offset of 32 when converting to Fahrenheit.
- Using °C and K interchangeably (they differ by 273.15).
