Convert kelvins to rankines
1 K = 1.8 °R — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
1.8°R
As a fraction: 9/5
1 K = 1.8 °R
How to convert kelvins to rankines
Multiply the number of kelvins by 1.8 to get rankines.
The exact factor is 1.8 — as a fraction, 9/5.
Kelvin: The SI base unit. Absolute zero is 0 K; there are no negative kelvins.
Rankine: Absolute scale with Fahrenheit-sized degrees.
