Just ConvertedCommon Scenarios
Weight conversion is widely used in logistics, trade, and scientific experiments. When buying overseas goods, you might need to convert pounds (lb) and ounces (oz) to kilograms and grams. In precious metal trading (like gold and diamonds), carats (ct) and grains (gr) are essential pricing units.
History & Background
Historically, weight measurement went hand in hand with early commercial trade. Ancient Romans used scales, giving rise to the word "Pound". In China, after unifying the six states, Qin Shi Huang standardized weights and measures, establishing the traditional 16-liang-per-jin system.
Conversion Details
Weight (mass) conversion is based on the kilogram (kg).
Common conversions: 1 lb ≈ 0.4536 kg, 1 oz ≈ 28.35 g, 1 jin = 500 g.
