Formulas for Converting Temperature Scales:


Celsius Temperature Conversion Formula
Celsius to Fahrenheit Conversion [°F] = [°C] × 9/5 + 32
Celsius to Kelvin Conversion [K] = [°C] + 273.15
Celsius to Rankine Conversion [°R] = [°C] × 9/5 + 491.67


Fahrenheit Temperature Conversion Formula
Fahrenheit to Celsius Conversion [°C] = ([°F] − 32) × 5/9
Fahrenheit to Kelvin Conversion [K] = ([°F] + 459.67) × 5/9
Fahrenheit to Rankine Conversion [°R] = [°F] + 459.67


Kelvin Temperature Conversion Formula
Kelvin to Celsius Conversion [°C] = [K] − 273.15
Kelvin to Fahrenheit Conversion [°F] = [K] × 9/5 − 459.67
Kelvin to Rankine Conversion [°R] = [K] × 9/5


Rankine Temperature Conversion Formula
Rankine to Celsius Conversion [°C] = [°R] × 5/9 − 273.15
Rankine to Fahrenheit Conversion [°F] = [°R] − 459.67
Rankine to Kelvin Conversion [K] = [°R] × 5/9
