About Weight Converter
Weight is the unit that quietly changes at every border. Groceries are weighed in pounds in the US and kilograms nearly everywhere else, shipping quotes flip between the two mid-invoice, and then there are three different "tons" waiting to ambush the unwary.
This converter spans milligrams to metric tons: the kitchen scale range (grams, ounces), the human range (kilograms, pounds), and freight (metric tons). One clarification up front, because it matters on shipping paperwork: the metric ton here is exactly 1,000 kilograms. That's different from the US short ton (2,000 lb) and the imperial long ton (2,240 lb), mixing them up on a freight quote is an expensive mistake.
Type a value, pick your units, and the swap button reverses the direction. The one ratio to memorize is 1 kilogram = 2.20462 pounds. From there you can sanity-check anything: a 70 kg person is about 154 lb, a 500 g package is just over a pound, and that "2 lb" bag of coffee is roughly 907 grams.

Tips for best results
- Memorize 1 kg ≈ 2.2 lb; it's close enough for grocery and luggage estimates.
- Comparing prices across countries? Convert both to $/kg, per-pound and per-kilo prices hide the real deal.
- On shipping paperwork, confirm which ton: metric (1,000 kg), US short (2,000 lb), or imperial long (2,240 lb).
- Medication and supplement doses live in milligrams, double-check decimal places, since 0.5 mg and 5 mg differ tenfold.
- Airlines weigh luggage in kg internationally: convert your bag's pounds before you pack, not at the counter.
- Precious metals use troy ounces (31.1 g), not the avoirdupois ounces (28.35 g) used for groceries, don't mix them.
