The kilogram (kg) is a unit of measurement used to measure mass, and is also used in everyday life to weigh things. It is part of the metric system, which is used around the world, including in science and everyday life. One kilogram is equal to 1,000 grams, and it's the base unit of mass in the International System of Units (SI).
In practical terms, a kilogram weighs almost the same as a litre of water or a medium-sized textbook. When studying GCSE Maths, you'll encounter kilograms when solving problems related to mass, weight, or converting measurement units. Understanding kilograms helps in measuring objects accurately, whether it's for cooking, packaging, or science experiments.
