### H2: Convert weight between metric and imperial — with the math shown
Weight conversions trip people up more than almost any other unit, because the everyday words hide real differences. A recipe from the US lists ounces while your scale reads grams; a package is quoted in pounds but the courier wants kilograms; and in the UK body weight is still spoken in stone. Most of the time you just want a number you can trust.
This converter covers the seven units people actually use: kilogram, gram, milligram, and tonne on the metric side, and pound, ounce, and stone on the imperial side. Type a value, choose what you're converting *from* and *to*, and the answer appears instantly. A swap button reverses the direction, and the all-units table expands a single value into every unit at once, so "1 kilogram" becomes 1000 g, 2.20462 lb, 35.274 oz, and 0.157473 stone on one screen.
The tool shows the exact conversion factor behind each result. A pound is 0.45359237 kilograms by international definition — an exact figure agreed in 1959 — and the tool states it so you can verify the answer rather than trust a black box. A stone is exactly 14 pounds; an ounce is exactly one-sixteenth of a pound.
It also handles the ambiguous units honestly. "Ton" can mean a metric tonne (1000 kg), a US short ton (907.18 kg), or a UK long ton (1016.05 kg), so the tool labels which one you're using. And the ounce here is the avoirdupois ounce used for everyday weight — not the troy ounce used for gold and silver, which is heavier. Everything runs on your own device using fixed factors, so there's nothing to upload, no account, and no connection needed once loaded.
