About Weight and Mass Units
Mass is a fundamental measurement of the amount of matter in an object, while weight is the force exerted on that mass by gravity. On Earth, mass and weight are often used interchangeably, but they are fundamentally different concepts.
The International System of Units (SI) base unit for mass is the kilogram (kg). Other metric units include grams (g), milligrams (mg), and metric tons (t). Imperial units include ounces (oz), pounds (lb), and tons.
Fun fact: The kilogram is the only SI base unit that still defined by a physical artifact rather than a fundamental physical property.
