How It Works

Temperature Converter

Formulas from Celsius

  • Fahrenheit: °F = (°C × 9/5) + 32
  • Kelvin: K = °C + 273.15
  • Rankine: °R = (°C + 273.15) × 9/5

    • Worked Example

    Convert 25°C to Fahrenheit, Kelvin, and Rankine.

    celsius = 25
    1. 01°F = (25 × 9/5) + 32 = 45 + 32 = 77°F
    2. 02K = 25 + 273.15 = 298.15 K
    3. 03°R = (25 + 273.15) × 9/5 = 298.15 × 1.8 = 536.67°R
