Comparison: Kelvin vs Celsius
When to Use Each Unit
Kelvin: Primary temperature scale in scientific research, physics, chemistry, and astronomy. Used when absolute temperature measurements are required.
Celsius: Standard temperature scale used worldwide for weather, cooking, medical measurements, and scientific applications. Official scale in most countries except the United States.
Common Conversion Values
- 273.15 K = 0°C (water freezing)
- 373.15 K = 100°C (water boiling)
- 310.15 K = 37°C (human body temperature)
- 0 K = -273.15°C (absolute zero)
About (symbol:
Definition: Kelvin (symbol: K) is the SI base unit of temperature, with 0 K representing absolute zero (-273.15°C). No degree symbol is used.
History: Proposed by William Thomson (Lord Kelvin) in 1848 based on absolute zero. Became an SI base unit in 1954, redefined in 2019 using the Boltzmann constant.
Current Use: Primary temperature scale in scientific research, physics, chemistry, and astronomy. Used when absolute temperature measurements are required.
Examples: Liquid nitrogen: 77 K, room temperature: 293 K, surface of Sun: 5778 K
About (symbol:
Definition: Celsius (symbol: °C) is a temperature scale where water freezes at 0°C and boils at 100°C at standard atmospheric pressure. Originally called centigrade.
History: Developed by Swedish astronomer Anders Celsius in 1742, originally with 0° as boiling point and 100° as freezing point. The scale was inverted after his death to the current form.
Current Use: Standard temperature scale used worldwide for weather, cooking, medical measurements, and scientific applications. Official scale in most countries except the United States.
Examples: Weather: -10°C to 40°C, cooking: 180°C oven, fever: 39°C, refrigerator: 4°C
