The Kelvin (K) scale is the absolute temperature scale used in scientific calculations, physics, and engineering. Unlike the Celsius (°C) scale, the Kelvin does not use degrees and starts at absolute zero (0 K), the coldest possible temperature, where molecular motion stops.
The Celsius scale, also known as centigrade, is widely used around the world for weather forecasts, cooking, and daily temperature measurement. It is based on the properties of water, with 0°C as the freezing point and 100°C as the boiling point at standard atmospheric pressure.
To convert Kelvin to Celsius, use this formula:
Celsius (°C) = Kelvin (K) - 273.15
For example, to convert 300 K to Celsius:
300 - 273.15 = 26.85°C

Absolute zero (0 K or -273.15°C) is the coldest possible temperature, where all atomic motion ceases.
The human body’s normal temperature is approximately 310.15 K (37°C or 98.6°F).
The Kelvin scale is commonly used in astrophysics to measure the temperature of stars, planets, and cosmic background radiation.
Scientists use Kelvin in cryogenics to study supercooled materials and superconductors.
The hottest temperature ever recorded on Earth was 331.15 K (58°C or 136°F) in Furnace Creek, California.
The Kelvin scale is named after William Thomson, 1st Baron Kelvin, a Scottish physicist who made significant contributions to thermodynamics. He was instrumental in defining absolute zero and formulating the laws of thermodynamics.
His work was essential in refrigeration, power generation, and space exploration. Today, Kelvin is the SI unit of temperature, used globally in scientific research, engineering, and space science.

Converting Kelvin to Celsius is straightforward—simply subtract 273.15 from the Kelvin value. While Celsius is widely used in daily life, Kelvin is the standard for scientific and engineering calculations, space exploration, and thermodynamics.
