Conversion Formulas Used

  • Celsius ↔ Fahrenheit:
    • °F = (°C × 9/5) + 32
    • °C = (°F − 32) × 5/9
  • Celsius ↔ Kelvin:
    • K = °C + 273.15
    • °C = K − 273.15
  • Fahrenheit ↔ Kelvin:
    • K = (°F − 32) × 5/9 + 273.15
    • °F = (K − 273.15) × 9/5 + 32
  • Celsius ↔ Rankine:
    • °R = (°C + 273.15) × 9/5
  • Fahrenheit ↔ Rankine:
    • °R = °F + 459.67
  • Kelvin ↔ Rankine:
    • °R = K × 9/5

Example Calculations

Example 1: Convert Fahrenheit to Celsius

  • Input: 98.6°F
  • Output: 37.00°C (rounded to 2 decimals)
  • Formula: °C = (°F − 32) × 5/9
