Formula and worked example
K = (°F − 32) × 5/9 + 273.15
Convert 68 °F to K: using K = (°F − 32) × 5/9 + 273.15, 68 °F = 293.15 K.
When you need this
Needed in US engineering and lab work when a formula needs an absolute temperature but the measurement was taken in Fahrenheit.
Questions people ask
What is 68 °F in K?
68 °F is 293.15 K.
What is the formula for degrees Fahrenheit to kelvins?
K = (°F − 32) × 5/9 + 273.15.
Why can't I just multiply by one number?
The scales start from different zero points, so you have to add or subtract an offset as well as scale the value.
How do I convert kelvins back to degrees Fahrenheit?
Use the reverse conversion: 293.15 K is 68 °F.
