About Kilograms
The kilogram (kg) is the SI base unit of mass - the fundamental unit from which all other mass measurements in the metric system are derived. Since 2019 it has been defined by fixing the Planck constant h to exactly 6.62607015 × 10⁻³⁴ J·s, replacing the 130-year-old International Prototype Kilogram (a platinum-iridium cylinder kept in Sèvres, France). The kilogram governs daily life worldwide: body weight in most countries, grocery shopping, luggage allowances, postal rates, freight pricing, and ingredient quantities in cooking all reference kilograms.
About Pounds
The avoirdupois pound (lb) is the primary unit of weight in the United States and United Kingdom for everyday use, equal to 16 ounces or exactly 453.59237 grams. It dominates American life: body weight, grocery produce, deli counter cuts, freight shipping costs, gym weights, and building material quantities are all measured in pounds and ounces. American recipes use pounds for meat and large quantities. The pound derives from the Roman 'libra pondo' (a pound by weight) - hence both the symbol 'lb' (from libra) and the British currency symbol '£'.
