What is Kelvin?
Kelvin (K) is the base unit of temperature in the International System of Units (SI). It starts at absolute zero (-273.15°C) where all molecular motion stops.
Scientific Importance
Kelvin is essential in physics, chemistry, and engineering. It's used in gas laws, thermodynamics, and scientific research where absolute temperature matters.
When Do You Need It?
Scientific calculations, physics problems, chemistry equations, astronomy, and any application requiring absolute temperature measurements.
Conversion Examples
Step-by-Step Example:
Convert 25°C to Kelvin:
1. Add 273.15: 25 + 273.15 = 298.15 K
Result: 25°C = 298.15 K
