273.15 Kelvin to Rankine
273.15 K = 491.67 °R
273.15 kelvins equals 491.67 degrees Rankine.
How to convert 273.15 K to °R
Use the formula °R = K × 9/5:
°R = 273.15 × 9/5°R = 491.67
So 273.15 K = 491.67 °R.
Rounded values and quick estimate
- Rounded to a whole number: 492 °R
- Rounded to one decimal place: 491.7 °R
This conversion is exact, so there is no need to estimate: it uses a fixed offset or the exact 9/5 factor.

About kelvin and rankine
The kelvin is the SI unit of temperature. It starts at absolute zero (0 K = −273.15 °C) and uses degrees the same size as Celsius, so it never goes negative.
The Rankine scale starts at absolute zero like Kelvin but uses Fahrenheit-sized degrees (0 °R = −459.67 °F). It is still used in some US engineering work.
