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 Avoirdupois Drams
An avoirdupois dram (dr av) is 1/16 of an avoirdupois ounce - approximately 1.772 grams. Part of the avoirdupois system that governs everyday trade weights in the UK and US, it was historically used to measure small quantities of goods and spices in commerce. While rarely used in modern commerce (having been replaced by grams in most applications), the avoirdupois dram still appears in some spice and herbalist contexts, in US gunpowder loading data (where charges are specified in grains and drams), and in archaic recipe books.
