  • Since 2019, the kilogram is defined by fixing the value of the Planck constant to exactly 6.62607015×10−346.62607015 \times 10^{-34} joule seconds, linking mass to fundamental physical constants.



  • Before this, it was defined by a physical platinum-iridium prototype.



  • It is the only SI base unit still using the prefix "kilo" in its name.



Key points:



  • 1 kg is the base unit of mass in the metric system



  • Defined using the Planck constant for high precision



  • Widely used globally in science, industry, and everyday life



The kilogram ensures accurate and universal mass measurements across the world.
