About Kilograms
The kilogram is the base unit of mass in the SI system. Until 2019, it was defined by a physical platinum-iridium cylinder stored in France. It is now defined by the Planck constant.
Real-World Examples
- A liter of water weighs exactly 1 kilogram
- The average adult human brain weighs about 1.4 kilograms
- A standard bag of sugar in most countries is 1 kilogram
💡 Did you know? In 2019, the kilogram was redefined based on the Planck constant rather than a physical artifact, making it the last SI base unit to be defined by a fundamental constant of nature.
