Facts

  • The Kelvin scale starts at absolute zero, the coldest possible temperature.
  • The cosmic microwave background radiation has a temperature of about 2.7 K.
  • The surface of the Sun is about 5,778 K (5,505°C).
  • Room temperature is approximately 293-298 K (20-25°C).

Frequently Asked Questions

0 Kelvin equals -273.15°C. This is absolute zero, the coldest possible temperature in the universe, where all thermal motion of particles theoretically stops.

The Kelvin scale is an absolute thermodynamic temperature scale that starts at absolute zero (0 K). It is the SI base unit of temperature, named after Lord Kelvin. Each unit increment is the same size as one degree Celsius.

The formula is simple: °C = K - 273.15. Just subtract 273.15 from the Kelvin value to get Celsius. For example, 300 K - 273.15 = 26.85°C.

273.15 K equals exactly 0°C. This is the freezing point of water and the key reference point that connects the Kelvin and Celsius scales.

Both scales have the same degree size, but different starting points. Celsius sets 0° at water's freezing point, while Kelvin sets 0 at absolute zero (-273.15°C). Kelvin is used in science because it has no negative values, making mathematical calculations more straightforward.
