    FAQ

    What is 640.37 Kelvin in Fahrenheit?

    640.37 K ≈ 693 °F

    What is the formula to convert Kelvin to Fahrenheit?

    °F = K × 9/5 − 459.67: multiply the kelvins by 9/5, then subtract 459.67. A change of 1 K is a change of 1.8 °F.

    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.
