What are kilograms and pounds?
When you’re converting between kilograms and pounds, it helps to understand what each of these units of measure represents.
Kilograms (kg)
A kilogram is a unit of mass in the metric system. It’s the base unit of mass in the International System of Units (SI), and it’s the unit of choice in science and in most countries worldwide. The kilogram was originally defined as the mass of one liter of water.
Pounds (lbs)
A pound is a unit of mass used mainly in the United States and a few other countries. It’s part of the Imperial and US customary systems of measurement.
It’s important to remember that mass is different from weight. Mass is a measure of how much matter an object contains, while weight is the force of gravity acting on that mass.
