How to use the Temperature Converter

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

  1. Multiply by 9/5: 100 × 1.8 = 180.
  2. Add 32: 180 + 32 = 212.
  3. 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).
