Frequently Asked Questions

Everything you need to know about Weight Converter.

Kilograms, grams, pounds, ounces, and metric tons. There is no stone unit and no US short ton.

Yes, results update in real-time as you type.

Yes, ounces and grams work for both industrial and kitchen use.

Yes, everything runs in your browser with no uploads.

No. A metric tonne is exactly 1,000 kg; a US short ton is 907.185 kg and a UK long ton is 1,016.047 kg. Freight and machinery specs often omit which one they mean, so check the source country before you compare prices per ton.

One stone is exactly 6.35029318 kg and one pound 0.45359237 kg, but this tool has no stone unit. Convert stone to pounds yourself by multiplying by 14 and adding the remainder, then enter the pounds here.

Yes — a troy ounce is 31.1035 g against 28.3495 g for the avoirdupois ounce. Precious metals are quoted in troy ounces, so comparing gold prices with gram-based jewellery weights requires that conversion.

Under the Hood: the Weight Converter explained properly

No marketing filler — just the mechanics, the trade-offs and the real limits, explained clearly.

How it actually works

Mass units (kilograms, grams, pounds and ounces) are each defined by their size in kilograms, the base, so a conversion multiplies into kilograms and divides out to the target, and the result also lists the same mass in the other common units at once.

What that means for your results

The pound is the exact 0.45359237-kilogram definition, so shipping and recipe figures stay consistent, and showing kilograms, grams and pounds together lets you sanity-check a value on one screen.

Where it falls short — honestly

It handles mass only, so stone, tonnes and troy ounces are not in the list, and it is a unit conversion rather than a scale: it cannot tell actual weight from dimensional weight, which couriers often bill on.

A real end-to-end workflow

Learn the pair that unlocks foreign recipes (one pound is about 454 grams), convert both actual and volumetric weight before choosing a courier, and keep one unit in a fitness log, using Length Converter for parcel dimensions and Unit Converter for wider needs.
