# Kelvin to degrees Rankine

**1 kelvin in degrees Rankine: 1 K = 1.8 °R**

°R = K × 9/5

To convert kelvin to degrees Rankine, multiply by 1.8. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is °R = K × 9/5. Both units measure temperature, so the conversion is a fixed formula that never changes. Temperature scales are the one common case where converting is not just multiplication — Celsius and Fahrenheit each put their zero in a different place, so an offset is applied as well as a scale factor.

## Common questions

### How many degrees Rankine are in one kelvin?

One kelvin equals 1.8 degrees Rankine. °R = K × 9/5.

### How do you convert kelvin to degrees Rankine?

Use °R = K × 9/5. So 10 K is 18 °R.

### How many kelvin are in one degree Rankine?

One degree Rankine equals 0.55556 kelvin, which is the reverse of the conversion above.
