Common mistakes
Confusing "ton" definitions - this uses the US short ton (2,000 lb); the UK long ton and metric tonne are both slightly different weights.
Mixing up weight (mass) with volume - a kilogram of feathers and a kilogram of lead weigh the same, even though they take up very different space.
Frequently asked questions
Is a US ton the same as a metric tonne?
No - a US short ton is 2,000 lb (about 907 kg), while a metric tonne is exactly 1,000 kg (about 2,205 lb). This calculator uses the US short ton.
Why do my kitchen scale and a shipping label use different units?
Different industries and regions default to different units by convention - grams and kilograms are standard in cooking and science, while pounds and ounces remain common in everyday US contexts.
How precise are these conversions?
They use the exact internationally defined conversion factors (like exactly 453.59237 grams per pound), so results are precise to the decimal places shown.
