100 kelvin is equal to -173.15 degrees celsius.
The conversion from kelvin to celsius involves subtracting 273.15 from the kelvin temperature. Since the kelvin scale starts at absolute zero, which is -273.15 degrees celsius, you adjust the kelvin value by this amount to get the equivalent celsius temperature.

Conversion Formula
To convert kelvin (K) to celsius (°C), subtract 273.15 from the kelvin temperature:
°C = K – 273.15
This formula works because the zero point of the kelvin scale (0 K) is absolute zero, which is -273.15°C on the celsius scale. Essentially, kelvin and celsius scales are offset by 273.15 degrees.
Example with 100 kelvin:
- Start with 100 K
- Subtract 273.15: 100 – 273.15 = -173.15
- Result is -173.15°C
Conversion Example
- Convert 200 kelvin to celsius:
- Take 200 K
- Subtract 273.15: 200 – 273.15 = -73.15
- Result: -73.15°C
- Convert 0 kelvin to celsius:
- Take 0 K
- Subtract 273.15: 0 – 273.15 = -273.15
- Result: -273.15°C
- Convert 300 kelvin to celsius:
- Take 300 K
- Subtract 273.15: 300 – 273.15 = 26.85
- Result: 26.85°C
- Convert 273.15 kelvin to celsius:
- Take 273.15 K
- Subtract 273.15: 273.15 – 273.15 = 0
- Result: 0°C

Conversion Definitions
Kelvin: Kelvin is a temperature scale used in science, starting at absolute zero where particles have minimum thermal motion. One kelvin increment equals one degree celsius, but kelvin does not use the degree symbol. It measures temperature from absolute zero upwards.
Celsius: Celsius is a temperature scale based on the freezing and boiling points of water, defined as 0°C and 100°C respectively at sea level. It is commonly used in everyday life and science, measuring temperature relative to the freezing point of water.
Conversion FAQs
Why does the kelvin to celsius conversion require subtracting 273.15?
The kelvin scale starts at absolute zero, which is the lowest possible temperature where particles stop moving. Absolute zero is -273.15 degrees on the celsius scale. Therefore, converting kelvin to celsius means shifting the scale down by 273.15 degrees to align the zero points.
Can kelvin values be negative like celsius?
No, kelvin values cannot be negative because the kelvin scale starts at absolute zero (0 K). Negative temperatures don’t exist on the kelvin scale since it represents absolute absence of thermal energy.
Is 100 kelvin a common temperature in everyday life?
100 kelvin is very cold compared to everyday temperatures, it’s about -173.15°C. This temperature is found in some scientific or industrial processes but is far below normal environmental temperatures.
How precise is the conversion between kelvin and celsius?
The conversion is exact when using 273.15 as the offset. Precision depends on decimal places used; scientific calculations often use more decimals, but 273.15 suffices for most practical purposes.
Does temperature scale choice affect calculations in physics?
Yes, using kelvin is crucial in physics because it starts at absolute zero, allowing direct proportionality in many formulas involving temperature, like gas laws. Celsius is more practical for daily use but less suited for theoretical physics.
