Acerca de Conversor de peso (kg, lb, stone, oz)
Every mass unit is a fixed number of kilograms. The pound has been exactly 0.45359237 kg since the 1959 international yard and pound agreement, so pounds, ounces (1/16 lb), stones (14 lb) and short and long tons all convert exactly. The kilogram itself has been defined since 2019 by a fixed value of the Planck constant.
The default converts 1 kg to 2.20462262185 lb, a repeating decimal shown to 12 significant figures. Body weight is the usual reason to convert: 70 kg is 154.32 lb, or just over 11 stone.
Weight here means mass, the sense in which scales and shops use the word. Precious metals use the troy ounce (31.1034768 g) rather than the ordinary ounce (28.349523125 g), and gems are weighed in metric carats of exactly 200 mg.

2.20462262 lb. The pound is defined as exactly 0.45359237 kg, so 1 kg = 1 ÷ 0.45359237 = 2.2046226218… lb, a decimal that never ends. The shortcut “multiply by 2.2” is 0.2% low: 100 kg is 220.46 lb, not 220.
How many kilograms are in a stone?
Exactly 6.35029318 kg. A stone is 14 lb, and 14 × 0.45359237 kg gives that figure. Stones are still used for body weight in the UK and Ireland; 11 st 7 lb is 161 lb, which is 73.03 kg.
What is the difference between a troy ounce and an ounce?
A troy ounce is 31.1034768 g and an ordinary (avoirdupois) ounce is 28.349523125 g, so the troy ounce is 9.7% heavier. Gold, silver and platinum prices are quoted per troy ounce. A troy pound has 12 troy ounces, while the ordinary pound has 16 ounces.
Is a ton the same as a tonne?
No. A tonne (metric ton) is 1,000 kg. A US short ton is 2,000 lb, 907.18474 kg, and a UK long ton is 2,240 lb, 1,016.0469088 kg. The long ton is 12% heavier than the short ton, so shipping and freight documents should state which one they use.
How many grams is a tola?
11.6638038 g. A tola is 180 grains, and a grain is exactly 64.79891 mg (NIST Handbook 44), so 180 × 64.79891 mg = 11.6638038 g. Gold is still traded by the tola in South Asia and the Gulf, where a 10-tola bar weighs 116.64 g.
