Kelvin (K), base unit of thermodynamic temperature measurement in the International System of Units.

While the celsius is a unit of temperature on temperature scale originally known as the centigrade scale.

0 K is also known as absolute zero. It is the point at which no further heat can be removed from a system because there is no molecular movement, so there is no lower temperature possible.

Similarly, this means the lowest possible Celsius temperature you can ever get is minus 273.15

**Formula to convert K to °C.**

To convert K to °C , we subtract 273.15 from the K.

**Temp. in Celsius = Temp. in Kelvin – 273.15**

**Example:**

Convert 546.3 K to Celsius.

**= 300.15 -273.15**

**= 27** **°C** .
