Convert Kelvin to Rankine

Convert kelvin to rankine by entering a value below.

1 K (kelvin) = 1.8 °R (rankine)

How to Convert Kelvin to Rankine

The kelvin and rankine are both units of temperature measurement. To convert kelvin to rankine, use the formula °R = K × 9/5.

Formula

°R = K × 9/5

Step-by-Step Example

Convert 100 K to rankine:

1
Convert 100 K to rankine

Formula: °R = K × 9/5

2
Multiply by 9/5

100 × 9/5 = 180

Answer

100 K = 180 °R

About These Units

Kelvin (K)

Kelvin (K) is the SI base unit for temperature, used in science and engineering. Absolute zero (0 K) is -273.15°C or -459.67°F—the coldest possible temperature where molecular motion stops. No degree symbol is used with Kelvin. Water freezes at 273.15 K. Named after Lord Kelvin.

Rankine (°R)

Rankine (°R) is an absolute temperature scale using Fahrenheit-sized degrees. Absolute zero is 0°R (-459.67°F). Water freezes at 491.67°R and boils at 671.67°R. Used in some US engineering applications, particularly thermodynamics. Named after Scottish engineer William Rankine.
