About Mass Converter

Mass Converter handles metric (tonnes, kilograms, grams, milligrams), avoirdupois imperial (long ton, short ton, hundredweight, stone, pound, ounce), and Troy ounces for precious metals. Useful for shipping invoices that switch between kg and lb across borders, gold pricing where Troy ounces matter, and gym/body-weight tracking where stones and kg mix. Mass vs weight is a physics nuance we leave aside here — this is a units-of-measure panel that switches numerals. Everything runs locally in your browser; no server call.

Best for

  • Shipping invoices that confuse kg and lb across countries
  • Gold and silver pricing where Troy ounces matter, not avoirdupois
  • Fitness tracking where someone reports weight in stones or pounds and you want kg

Pros

  • +Metric, imperial, Troy, and apothecary units in one panel
  • +All values update as you type — every unit visible at once
  • +Local JavaScript only; no signup, no uploads, works offline

Cons

  • −No mass-vs-weight-force distinction (gravitational weight in newtons)
  • −Specialty scales (carat for gemstones) are not included

Frequently Asked Questions

Why is a Troy ounce different?
A troy ounce is about 31.10 grams, while a regular (avoirdupois) ounce is about 28.35 grams. Troy ounces are the standard for gold, silver, platinum, and palladium; this tool makes the distinction explicit so you don't accidentally price precious metals wrong.
What's the difference between a long ton, a short ton, and a metric tonne?
A metric tonne is 1,000 kg. A short ton (US) is 2,000 lb (~907 kg). A long ton (UK) is 2,240 lb (~1,016 kg). The panel shows all three side by side so shipping quotes from different countries don't get confused.
Does this account for mass versus weight?
No — this is a pure units-of-measure converter. Weight (in newtons) depends on local gravity; mass (in kg) is invariant. If you need weight-force in different gravity fields, use a physics calculator.
Can I convert micrograms or carats?
Milligrams and micrograms are supported under metric. Carats for gemstones (1 carat = 200 mg) are not currently included — paste the value in milligrams instead.
Are my inputs uploaded?
Never. The entire conversion runs as local JavaScript in your browser. Your inputs are never sent anywhere.
