Kelvin to Celsius Converter
Convert Kelvin to Celsius for science, engineering, and physics temperature reference.
How It Works
Formula: K to °C = value × 1 − 273.15
Example: 300 K = 26.85 °C
Note: Kelvin converts to Celsius using C = K − 273.15, the SI temperature standard used in science.
Common Uses
Rounding Rule
Rounded to 2 decimal places
Error Margin
±0.01°C
Precision Guidance
For science, keep 2 decimal places. For estimates, round to 1 decimal.
Common Mistakes
Kelvin does not use the degree symbol (°). Write 300 K, not 300°K. Subtract 273.15, not 273, for precision.
Frequently Asked Questions
What is 300 K in Celsius?
300 K equals 26.85°C using the formula C = K − 273.15.
How do I convert Kelvin to Celsius?
Subtract 273.15 from the Kelvin value. For example, 300 K − 273.15 = 26.85°C.
What is 0 Kelvin?
0 K is absolute zero, equal to −273.15°C, the lowest possible temperature.
Is Kelvin used in everyday life?
No, Kelvin is mainly used in science and engineering. Celsius and Fahrenheit are for everyday temperatures.
