# Temperature Conversion Factors

## from Fahrenheit °F to Celsius °C calculation:

Subtract 32 from the Fahrenheit figure, multiply by 5, then divide by 9 to get Centigrade figure.

## from Celsius °C to Fahrenheit °F calculation:

Multiply Centigrade figure by 9, divide by 5, then add 32 to get Fahrenheit figure.

## Kelvin calculation

To calculate Kelvin figure, simply add 273.15 number to the Celsius temperature degree and you get the temperature reading in Kelvin thermodynamic temperature unit:

K = °C + 273.15 and correspondingly.

Take the figure and you can manually convert it to Fahrenheit with:

K = °F + 459.67 × 5/9

Where the 5/9 is number 0.556 and, precisely even more accurate 0.55555555555555555555555555555556 (32 decimal points) to end up with the exact 273.15 mark correct metrics.

The formulae for temperature with minus degrees readings:

K = 273.15 − °C (below zero C value used)
K = 459.67 − °F × 5/9 (minus F value used)

Kelvin is not associated with thermal ° degree symbol just with capital letter K. Zero kelvins, 0 K, equals to coldest possible temperature that can be measured "absolute zero" which is the thermodynamic (absolute) temperature -459.67°F or -273.15°C on scales.
