Exact anchors273.15 K = 491.67 °R

°R → KK = °R × 5/9

iTemperature conversions are affine (scale + offset), not a single multiply. Absolute zero is 0 K = −273.15 °C = −459.67 °F = 0 °R.

How to use

Choose K → °R or °R → K

Use the tabs to switch direction. Forward mode needs kelvin; reverse uses the opposite unit.
