Understanding kg, lbs, and Stone – The Three Common Body Weight Units

Body weight is reported in three different units depending on which country you are in, and the confusion between them is one of the most frequent reasons people search for weight converters. In most of the world, kilograms (kg) are standard — 1 kg = 2.20462 pounds exactly. In the United States, pounds (lbs) are used exclusively. In the UK and Ireland, stone is still widely used for body weight even though the metric system is official: 1 stone = 14 pounds = 6.35029 kg. A person who weighs 75 kg is 165.35 lbs or 11 stone 11.3 lbs — three completely different numbers for the same weight. For gym tracking and health apps this conversion is needed constantly. The formula from kg to lbs is simple: multiply by 2.20462. From lbs to kg: divide by 2.20462. Stone is slightly more involved: divide the total pounds by 14 to get stone (integer part) and the remainder gives the pounds component.

Metric Tons, US Tons, Imperial Tons, and Carats – Industrial and Specialty Units

When dealing with heavy industrial goods or precious stones, three less obvious weight units become important. The metric ton (tonne, MT) equals exactly 1,000 kg and is used globally in shipping, agriculture, and commodity trading. The US short ton equals 2,000 lbs (≈ 907.185 kg) and is the default "ton" in US commerce. The imperial long ton equals 2,240 lbs (≈ 1,016 kg) and is used in UK shipping contexts — the difference between a US ton and an Imperial ton is 240 lbs, which matters significantly in bulk cargo pricing. For gemstones and precious metals, the carat (ct) is the standard: 1 ct = 0.2 grams = 200 milligrams. A 1-carat diamond weighs 0.0002 kg — a tiny fraction that the converter handles precisely. Note that carat (ct) for weight is distinct from karat (kt), which measures gold purity on a 0–24 scale and has nothing to do with mass.
