About Kelvin
Kelvin is the SI base unit of temperature. It starts at absolute zero (−273.15°C), the theoretical lowest possible temperature where molecular motion stops. It is used extensively in science, engineering, and astronomy.
Real-World Examples
- Absolute zero is 0 K (−273.15°C)
- The surface of the Sun is approximately 5,778 K
- Liquid nitrogen boils at 77 K (−196°C)
💡 Did you know? Kelvin is the only SI unit that is not preceded by the degree symbol. You say '300 Kelvin,' not '300 degrees Kelvin.' It is named after Lord Kelvin (William Thomson), who first proposed the absolute temperature scale in 1848.
About Celsius
The Celsius scale is the standard temperature scale used by most countries worldwide. Water freezes at 0°C and boils at 100°C at standard atmospheric pressure. It was developed by Swedish astronomer Anders Celsius in 1742.
Real-World Examples
- Human body temperature is about 37°C
- A comfortable room temperature is 20 to 22°C
- The hottest temperature ever recorded on Earth was 56.7°C in Death Valley, California
💡 Did you know? Celsius originally designed his scale backwards, with 100° as the freezing point and 0° as the boiling point. It was reversed after his death by Carl Linnaeus.
