Frequently asked questions

Is a US ton the same as a metric tonne?

No. A US (short) ton is 2,000 lb ≈ 907.18 kg; a metric tonne is exactly 1,000 kg; a UK (long) ton is 2,240 lb. This converter uses the US short ton and the kilogram, and labels them.

How many ounces are in a pound?

Exactly 16 avoirdupois ounces. (Precious metals use troy ounces instead — a different system covered by the gold and silver calculators.)

14 pounds. Stone is still common for body weight in the UK and Ireland: 11 stone = 154 lb.
