What is -65 Fahrenheit in Kelvin?

Answer

-65 °F ≈ 219.26 K

Gas-law formulas (pV = nRT) and the Stefan–Boltzmann law take absolute temperature: in kelvins, not in °F.

FAQ

What is -65 Fahrenheit in Kelvin?

-65 °F ≈ 219.26 K

What is the formula to convert Fahrenheit to Kelvin?

K = (°F + 459.67) × 5/9: add 459.67 to the degrees Fahrenheit, then multiply by 5/9. A change of 1 °F is a change of 5/9 K.

What is absolute zero in Celsius and Fahrenheit?

0 K = -273.15 °C = -459.67 °F: the lowest possible temperature. Kelvins count from it, so a temperature in kelvins is never negative.

Why is the kelvin written without a degree sign?

Since 1967 the kelvin has been an SI unit in its own right, not a degree: a temperature in kelvins is written with the symbol K alone and read as “kelvins”; only °C and °F keep the degree sign.

At what temperature do Kelvin and Fahrenheit show the same number?

At 574.5875: 574.5875 K = 574.5875 °F — the only such point.
