About Weight and Mass

While often used interchangeably in everyday language, weight and mass are technically different. Mass is the amount of matter in an object, while weight is the force exerted on that mass by gravity. However, for practical conversions on Earth, these terms are used synonymously.

The metric system uses grams and kilograms as its base units. It's a decimal system where each unit is related by powers of 10, making conversions straightforward.
