Degrees Fahrenheit to Kelvins Converter

Convert to Celsius first — subtract 32 and multiply by 5/9 — then add 273.15.

70 °F = 294.261111111 K

Convert kelvins to degrees Fahrenheit instead

Formula

K = (°F − 32) × 5/9 + 273.15

Worked example

Convert 70 degrees Fahrenheit to kelvins

  1. Use K = (°F − 32) × 5/9 + 273.15
  2. Substitute 70 °F: 294.261 K

70 °F = 294.261 K

Good to know

Absolute zero is −459.67 °F. Engineers in the US sometimes use the Rankine scale, which has Fahrenheit-sized degrees starting at absolute zero (°R = °F + 459.67); kelvin is the SI equivalent, with Celsius-sized degrees.

About these units

Degree Fahrenheit (°F)
Water freezes at 32 °F and boils at about 212 °F. A change of 1 °F is 5/9 of a change of 1 °C.
Kelvin (K)
The SI unit of temperature. 0 K is absolute zero; 0 °C is exactly 273.15 K. Kelvin is written without a degree sign.
