# Kelvin to Celsius Conversion – K to °F

LAST UPDATE: October 26th, 2020

## Formula – How to convert Kelvin (K) to Celsius (°C)

°C = K – 273.15

Subtract 273.15 from the temperature in Kelvin.

#### EXAMPLE

Find 293.15K in Celsius:

293.15K – 273.15K = 20°C

## What is the difference between Celsius and Kelvin?

Celsius and Kelvin both operate on the same interval – an increase in one degree of one is the same as an increase of one degree in the other.

Celsius is benchmarked between the freezing point of water (0°C, or 273.15K) and the boiling point of water (100°C, or 373.15K).

Kelvin is benchmarked from the temperature Absolute 0, the coldest temperature possible in the universe.

Unlike Celsius, Fahrenheit, and Rankine, Kelvin does not use a degree scale (°). The units of temperature in kelvin are simply noted as “K” not “°K”

## Who uses Celsius and Kelvin?

Celsius is a common temperature scale (along with Fahrenheit) for temperature measurements, specifically weather.

Kelvin is used in the scientific community, specifically the physical sciences.

## What are other common temperature scales?

Fahrenheit and Rankine are two other common temperature scales.

Fahrenheit uses a scale of 32°F for the freezing point of water and 212°F for the boiling point of water.

Rankine is related to Fahrenheit the same way that Kelvin is to Celsius. 0°R (0 degrees Rankine) is absolute 0, and the scale increases at the same interval as Fahrenheit from there.
