A liter of water weighs 1 kg. A typical pineapple is about 1 kg. An average adult cat weighs 4–5 kg. In grams, that gives you: 1 kg = 1000 g, 10 kg = 10000 g, 100 kg = 100000 g.
The kilogram (kg) is the SI base unit of mass. Since the 2019 redefinition it is defined by fixing the Planck constant to exactly 6.62607015 × 10⁻³⁴ J·s, replacing the old International Prototype Kilogram artifact. In everyday use, the kilogram is the global standard for body weight, groceries, and engineering specifications.
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
