The result of converting 0 kelvin to celsius is -273.15°C.
Since 0 kelvin is the absolute zero point where all thermal motion stops, it is exactly -273.15 degrees Celsius. This is the lowest possible temperature, representing a theoretical limit where particles have minimum energy. Therefore, 0 kelvin equals -273.15°C.

Conversion Formula
The conversion from kelvin to celsius involves subtracting 273.15 from the kelvin value. Kelvin is an absolute scale starting at zero, while Celsius is based on water’s freezing point (0°C) and boiling point (100°C). The formula works because the two scales are offset by 273.15 degrees. For example, if you have 300 Kelvin, subtracting 273.15 gives 26.85°C.
Conversion Example
- Convert 50 Kelvin to Celsius:
- Step 1: Write the formula: Celsius = Kelvin – 273.15
- Step 2: Substitute 50 Kelvin: Celsius = 50 – 273.15
- Step 3: Calculate: -223.15°C
- So, 50 Kelvin is -223.15°C.
- Convert 300 Kelvin to Celsius:
- Step 1: Celsius = 300 – 273.15
- Step 2: Calculate: 26.85°C
- Thus, 300 Kelvin is 26.85°C.
- Convert 273 Kelvin to Celsius:
- Step 1: Celsius = 273 – 273.15
- Step 2: Result: -0.15°C
- So, 273 Kelvin equals -0.15°C.

Conversion Definitions
Kelvin
Kelvin is an absolute temperature scale starting at zero, where particles have minimum thermal energy. It has no negative numbers and is used mainly in scientific contexts to measure thermodynamic temperature based on absolute zero.
Celsius
Celsius is a temperature scale based on water’s freezing point at 0°C and boiling point at 100°C under standard conditions. It is widely used for everyday temperature measurement, with degrees offset from Kelvin by 273.15.
Conversion FAQs
Why is absolute zero set at -273.15°C?
Absolute zero is the temperature where particles have minimal energy, and at this point, the Kelvin scale reaches 0. Since Celsius is offset by 273.15 degrees from Kelvin, absolute zero in Celsius is -273.15°C. This creates a zero point for the Kelvin scale that aligns with the lowest possible temperature.
Can temperature in kelvin ever be negative?
No, kelvin cannot be negative because it is based on absolute zero, the lowest possible temperature. Negative Kelvin values would imply temperatures below absolute zero, which violate thermodynamic principles because particles cannot have less than zero thermal energy.
What does a temperature of 0 Kelvin indicate physically?
0 Kelvin, or absolute zero, indicates a state where particles have the least possible energy. At this temperature, thermal motion stops, and it’s theoretically impossible to reach or go below this point. It is used as a baseline in thermodynamics and quantum mechanics.
