Conversion Formulas
UnitBuddy uses the following formulas for accurate unit conversions:
Temperature Conversions
Celsius to Fahrenheit: °F = (°C × 9/5) + 32
Fahrenheit to Celsius: °C = (°F - 32) × 5/9
Celsius to Kelvin: K = °C + 273.15
Kelvin to Celsius: °C = K - 273.15
Fahrenheit to Kelvin: K = (°F - 32) × 5/9 + 273.15
Kelvin to Fahrenheit: °F = (K - 273.15) × 9/5 + 32
Rankine to Celsius: °C = (°R - 491.67) × 5/9
Celsius to Rankine: °R = (°C × 9/5) + 491.67
