Kilograms Is More Than You Ever Imagined – Spoiler: It’s Not What You Think When you see a number like “1 kilogram,” it seems straightforward, something you rely on every day without deeper thought. But dig a little deeper, and you’ll discover that kilograms are far more than just a weight unit—they’re a gateway to understanding physics, health, sustainability, and even economics. The truth about kilograms might just surprise you. ### What Exactly Is a Kilogram? At its core, a kilogram is the SI base unit of mass in the International System of Units (SI). Defined by actual physical artifacts until 2019, the kilogram was historically tied to the International Prototype of the Kilogram (IPK)—a platinum-iridium cylinder stored in France. Since that redefinition, it’s now defined by Planck’s constant, linking mass to fundamental physics.
