About Kelvin
The Kelvin is the base unit of thermodynamic temperature in the International System of Units (SI). It is defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water.
Facts About Kelvin
- 0 K is absolute zero, the lowest possible temperature
- No negative temperatures exist on the Kelvin scale
- Water freezes at 273.15 K and boils at 373.15 K (at sea level)
- Named after Irish-Scottish physicist William Thomson, 1st Baron Kelvin (1824–1907)
- The only SI temperature unit that does not use the degree symbol (°)
Common Uses
- Scientific research and thermodynamics
- Color temperature in lighting and photography
- Astronomy and space science
- Low-temperature physics experiments
- Semiconductor manufacturing
History
The Kelvin scale was proposed by William Thomson (Lord Kelvin) in 1848. It was designed to provide an absolute thermodynamic temperature scale, independent of any specific substance's properties. The scale was redefined in 2019 based on the Boltzmann constant, ensuring it remains stable and precise for scientific applications.
About Celsius
The Celsius scale, also known as the centigrade scale, is a temperature scale based on the freezing point of water at 0°C and the boiling point of water at 100°C (at standard atmospheric pressure).
Facts About Celsius
- Water freezes at 0°C and boils at 100°C (at sea level)
- Named after Swedish astronomer Anders Celsius (1701–1744)
- Used by most countries worldwide
- The official SI unit for temperature intervals is the degree Celsius
- Normal human body temperature is approximately 37°C
Common Uses
- Weather forecasts in most countries
- Scientific measurements and research
- Cooking and food preparation
- Medical temperature monitoring
- Climate and environmental studies
History
The Celsius scale was originally developed by Anders Celsius in 1742. Interestingly, Celsius initially proposed the reverse scale (0° for boiling and 100° for freezing), which was later inverted to the form we use today by Carl Linnaeus. The scale was renamed "Celsius" in 1948 to honor its creator.

Conversion Examples
Convert 1 Kelvin to Celsius
- Conversion Formula: °C = K - 273.15
- Calculation: 1K - 273.15 = -272.15°C
Convert 10 Kelvin to Celsius
- Conversion Formula: °C = K - 273.15
- Calculation: 10K - 273.15 = -263.15°C
Convert 100 Kelvin to Celsius
- Conversion Formula: °C = K - 273.15
- Calculation: 100K - 273.15 = -173.15°C
Convert 1,000 Kelvin to Celsius
- Conversion Formula: °C = K - 273.15
- Calculation: 1,000K - 273.15 = 726.85°C
