Weight & Mass Conversion Guide
Weight and mass are often used interchangeably in everyday life, though they are technically different. Mass is the amount of matter in an object (measured in kg, grams, etc.), while weight is the force of gravity on that mass. On Earth, they are proportional, so the terms are commonly used together.
The metric system uses the kilogram (kg) as the base unit. The imperial system uses pounds (lbs) and ounces (oz). The UK also uses stone for body weight.
