Kelvin: (K) scale is the SI (International System of Units) base unit for temperature measurement. It is widely used in science, physics, engineering, and astronomy because it is based on absolute zero, the lowest possible temperature in the universe.

Interesting Facts:
- 0 K = Absolute zero (-273.15°C or -459.67°F), the coldest possible temperature where all molecular motion theoretically stops. Absolute zero can never be reached in reality, but scientists have come extremely close—down to 38 picokelvin (pK), which is 38 trillionths of a degree above absolute zero (0 Kelvin)
- Kelvin does not use degrees (°). Unlike Fahrenheit (°F) or Celsius (°C), Kelvin is written without a degree symbol.
Interesting Facts:
- Originally called the "centigrade" scale because it was divided into 100 degrees between freezing and boiling points. It was renamed Celsius in 1948 to honor Anders Celsius, the Swedish scientist who created it in 1742.
- Anders Celsius’ original scale was reversed. He initially defined 100°C as freezing and 0°C as boiling, but it was later flipped to the modern standard.
- Water doesn't always boil at 100°C. At higher altitudes (e.g., in the mountains), lower air pressure makes water boil at lower temperatures.
- Death Valley holds the record for the highest air temperature on the planet. On 10 July 1913 it reached 56.7°C
- The coldest place on Earth is the East Antarctic Plateau, where temperatures can drop below -92° Celsius.
