101 kelvin equals -172.15 degrees celsius.
To convert kelvin to celsius, you subtract 273.15 from the kelvin temperature. Since kelvin and celsius scales differ by a fixed offset, the conversion is direct and simple subtraction.

Conversion Formula
The formula used to convert kelvin (K) to celsius (°C) is:
°C = K – 273.15
This works because the kelvin scale starts at absolute zero, which is -273.15°C. The two scales have equal increments, so the only difference between values is the zero point. So by subtracting 273.15 from the kelvin value, you get the equivalent temperature in celsius.
For example, converting 101 K to °C:
- Start with 101 kelvin.
- Subtract 273.15: 101 – 273.15 = -172.15.
- The result is -172.15 °C.
Conversion Example
- Convert 300 K to °C:
- Take 300 kelvin.
- Subtract 273.15: 300 – 273.15 = 26.85.
- Result is 26.85 °C.
- Convert 0 K to °C:
- 0 kelvin.
- 0 – 273.15 = -273.15.
- Absolute zero in celsius.
- Convert 150.5 K to °C:
- 150.5 kelvin.
- 150.5 – 273.15 = -122.65.
- Means very cold temperature.
- Convert 400 K to °C:
- 400 kelvin.
- 400 – 273.15 = 126.85.
- High temperature in celsius scale.
- Convert 273.15 K to °C:
- 273.15 kelvin.
- 273.15 – 273.15 = 0.
- Water freezing point at sea level.

Conversion Definitions
Kelvin: Kelvin is the SI unit of temperature used in science and engineering, starts at absolute zero where all molecular motion theoretically stops. Unlike celsius or fahrenheit, kelvin scale does not use degrees or negatives and is based on thermodynamic temperature.
Celsius: Celsius scale measures temperature relative to water’s freezing and boiling points, set at 0°C and 100°C respectively at sea level. It is commonly used in everyday settings and scientific fields, providing a scale with positive and negative values.
Conversion FAQs
Can kelvin temperatures be negative?
No, kelvin temperatures cannot be negative because kelvin starts at absolute zero, the lowest possible temperature. Negative kelvin values do not exist physically, while celsius and fahrenheit scales can have negative values.
Why is kelvin used instead of celsius in science?
Kelvin is preferred in science because it’s an absolute scale based on fundamental physical laws, such as absolute zero. This makes calculations in thermodynamics and physics more consistent and meaningful, avoiding negative numbers that can complicate formulas.
How precise is the conversion from kelvin to celsius?
The conversion is exact to the decimal scale used, since it’s a simple subtraction of 273.15. Precision depends on the number of decimal places used; scientific work often requires four or more decimal places for accuracy.
What happens if I convert celsius to kelvin and back?
Converting celsius to kelvin and back will give you the original value, provided you keep the decimal precision. This is because the two scales differ by a fixed amount, so subtracting and adding 273.15 reverses the operation exactly.
Is -172.15 °C dangerously cold for humans?
Yes, -172.15 °C is far below freezing and lethal to humans without protection. Such temperatures exist only in outer space or specialized laboratory conditions, not naturally on Earth’s surface.
