How do I convert degrees Fahrenheit back to kelvins?

Use the reverse converter: 1 degree Fahrenheit equals 255.928 K.

Is this converter accurate?

Yes. It uses the exact SI/NIST definitions of each unit and shows up to 6 significant digits.

To convert kelvins to degrees Fahrenheit, use the formula °F = K × 9/5 − 459.67.

°F = K × 9/5 − 459.67

120 K → °F = K × 9/5 − 459.67 → -243.67 °F

Kelvin and Rankine start at absolute zero, so negative values are physically impossible.

Kelvin (K): The SI base unit of temperature, with zero at absolute zero. Named after Lord Kelvin and used in physics and chemistry.
Degree Fahrenheit (°F): Used for everyday temperatures in the US and a few other countries. Proposed by Daniel Fahrenheit in 1724; water freezes at 32 °F and boils at 212 °F.
