72 kelvin equals -201.15 degrees celsius.
To convert kelvin to celsius, subtract 273.15 from the kelvin temperature. So, for 72 kelvin, subtracting 273.15 gives the temperature in celsius, resulting in -201.15°C, which is very cold compared to everyday temperatures.

Conversion Formula
The formula to convert kelvin (K) to celsius (°C) is: °C = K – 273.15. This works because kelvin and celsius scales are offset by 273.15 units but have the same incremental value.
Every kelvin unit is equal to one degree celsius, but zero kelvin means absolute zero, the coldest possible temperature. So to find celsius from kelvin, subtract 273.15 from the kelvin temperature.
Example calculation for 72 kelvin:
- Start with 72 K
- Subtract 273.15: 72 – 273.15 = -201.15
- Result is -201.15°C
Conversion Example
- Convert 300 kelvin to celsius:
- 300 – 273.15 = 26.85°C
- So 300 K equals 26.85°C, a warm room temperature.
- Convert 0 kelvin to celsius:
- 0 – 273.15 = -273.15°C
- This is absolute zero, the coldest temperature possible.
- Convert 150 kelvin to celsius:
- 150 – 273.15 = -123.15°C
- This temperature is extremely cold, below freezing point.
- Convert 500 kelvin to celsius:
- 500 – 273.15 = 226.85°C
- This is much hotter than boiling water.

Conversion Definitions
Kelvin: Kelvin is the base unit of temperature in the International System of Units. It starts at absolute zero, the lowest possible temperature, where all molecular motion stops. The kelvin scale does not use degrees, and increments are the same size as celsius degrees.
Celsius: Celsius is a temperature scale based on the freezing and boiling points of water at sea level. Zero degrees celsius is the freezing point, and 100 degrees is boiling. It’s widely used globally for everyday temperature measurement and scientific purposes.
Conversion FAQs
Why do we subtract 273.15 to convert kelvin to celsius?
The kelvin scale starts at absolute zero (0 K), which equals -273.15°C. Since both scales use the same size increments, subtracting 273.15 shifts the kelvin value down to match the celsius zero point. This makes the conversion straightforward and consistent.
Can kelvin temperatures be negative?
No, kelvin is an absolute scale starting at absolute zero, the coldest temperature possible. Negative kelvin values don’t exist because that would imply temperatures below absolute zero, which is physically impossible under current scientific understanding.
Is the kelvin scale used in everyday weather reports?
Kelvin is mainly used in science and engineering, not daily weather forecasts. Weather temperatures are usually given in celsius or fahrenheit because they relate better to human experience, while kelvin is more useful for scientific measurements involving thermodynamics.
How precise is the kelvin to celsius conversion?
The conversion is exact when you subtract 273.15, but practical accuracy depends on the precision of the measurement devices. The decimal 273.15 is a defined constant, so no rounding errors exist in the theoretical formula itself.
Does converting kelvin to celsius affect temperature intervals?
No, the size of one kelvin equals one degree celsius. Only the zero points differ. Therefore, temperature differences or intervals remain the same when converting between the scales.
