How it works
We use K = deg C + 273.15.
Exact relationship: K = deg C + 273.15
Example: 0 deg C = 273.150 K.
Notes: Results are rounded in the default view.
Examples
- 0 deg C = 273.150 K
- 25 deg C = 298.150 K
- 100 deg C = 373.150 K
FAQ
What physical quantity do degrees Celsius and kelvins express?
Degrees Celsius express temperature on a metric-friendly scale used heavily in science, engineering, and international technical work. Kelvins express absolute thermodynamic temperature and are used where physical calculations need an absolute zero reference.
What is the difference between degrees Celsius and kelvins?
Degrees Celsius and kelvins both express temperature, but their zero points and scaling conventions differ, so temperature conversions often require both multiplication and an offset.
What is the history of the degree Celsius?
The Celsius scale was developed from the centigrade system and became the dominant everyday and technical temperature scale in most of the world.
What is the history of the kelvin?
The kelvin grew out of thermodynamics and modern SI standardization as the absolute temperature scale.
Were the degree Celsius and kelvin discovered by a specific person?
Celsius was created as a defined scale associated with Anders Celsius and later standardized, not discovered as a natural object. The kelvin was created through thermodynamic theory and standardization work rather than discovered by one person alone.
Where are degrees Celsius and kelvins used in science and engineering?
Degrees Celsius are used in laboratories, industrial processes, environmental control, standards documents, and international engineering communication. Kelvins are used in physics, thermodynamics, materials science, simulation, and standards-based engineering calculations.
Why are temperature conversions different from simple unit ratios?
Temperature scales can have different zero points, so many conversions need both a scale factor and an offset rather than a single multiplication constant.
Can I trust this for critical calculations?
Use this for convenience and verify against your governing standard, specification, or process requirement for critical work. Temperature interpretation often depends on context, instrumentation, and tolerance.
