1.4 kelvin is equal to -271.75 degrees celsius.
To convert kelvin to celsius, you subtract 273.15 from the kelvin value. Since 1.4 kelvin is very close to absolute zero, its celsius equivalent is a very low negative temperature.

Conversion Formula
The formula to convert kelvin (k) to celsius (°C) is:
°C = K – 273.15
Because kelvin and celsius scales both measure temperature but have different starting points, you subtract 273.15 from the kelvin value to get celsius. This works since 0 K equals -273.15 °C, so any kelvin value shifted by this amount gives the equivalent celsius temperature.
Example:
- Given 1.4 K
- Subtract 273.15: 1.4 – 273.15 = -271.75 °C
- So, 1.4 K equals -271.75 °C
Conversion Example
- Convert 300 K to Celsius:
- Start with 300 K
- Subtract 273.15: 300 – 273.15 = 26.85 °C
- Result: 26.85 °C
- Convert 0 K to Celsius:
- Start with 0 K
- Subtract 273.15: 0 – 273.15 = -273.15 °C
- Result: -273.15 °C which is absolute zero
- Convert 100 K to Celsius:
- Start with 100 K
- Subtract 273.15: 100 – 273.15 = -173.15 °C
- Result: -173.15 °C
- Convert 500 K to Celsius:
- Start with 500 K
- Subtract 273.15: 500 – 273.15 = 226.85 °C
- Result: 226.85 °C

Conversion Definitions
K (Kelvin): Kelvin is the base unit of temperature in the International System of Units. It measures absolute temperature starting at absolute zero, where all thermal motion ceases. The kelvin scale does not use degrees and is commonly used in scientific contexts.
Celsius: Celsius, also known as centigrade, is a temperature scale used for everyday temperature measurement. It sets 0 °C at water freezing point and 100 °C at boiling point under standard atmospheric pressure, providing a relative scale based on water’s phase changes.
Conversion FAQs
Why does the kelvin scale start at 0 but celsius does not?
The kelvin scale starts at absolute zero, which is the lowest limit of thermal energy possible, meaning no particle motion. Celsius is based on water’s freezing and boiling points, so it is offset by 273.15 degrees from kelvin to represent familiar temperature ranges.
Can a kelvin temperature be negative?
No, kelvin values cannot be negative because the scale starts at absolute zero, the point where particles have minimum thermal energy. Negative kelvin would imply less than absolute zero, which is physically impossible in classical thermodynamics.
Why subtract 273.15 to convert kelvin to celsius?
Because the kelvin scale is offset from celsius by exactly 273.15 degrees. Zero kelvin equals -273.15 °C. So, subtracting 273.15 from any kelvin value shifts the scale to celsius, aligning with water’s freezing point at zero degrees.
How accurate is the 273.15 value in conversions?
The value 273.15 is defined precisely as the difference between the kelvin and celsius scales. It is exact for conversion purposes, though real-world measurements can slightly vary due to experimental limitations and environmental factors.
Is kelvin used outside science?
Kelvin is mostly used in scientific and engineering fields where precise temperature measurement is required. Everyday temperature reporting uses celsius or fahrenheit, as kelvin values are less intuitive for common experiences.
