Kilogram
The kilogram (kg) is the base unit of mass in the International System of Units (SI). It is defined by the Planck constant (6.62607015 Ć 10-34 JĀ·s), making it one of the most precise measurements. Originally tied to the mass of a liter of water in 1794, it later relied on a platinum-iridium cylinder prototype. Despite minor changes, the kilogram is still trusted globally for science, the military, and everyday applications.
