Frequently Asked Questions about the Weight Converter
How many grams are in a pound?
1 avoirdupois pound equals exactly 453.59237 grams - a fixed international standard since 1959. That means 1 kilogram is about 2.204623 pounds. The calculator uses this exact factor for all conversions involving pounds, ounces, stones, and US tons.
How heavy is a stone?
1 stone equals exactly 14 pounds, which works out to about 6.350293 kg. The unit is still in everyday use in the UK and Ireland for body weight, though it rarely appears on medical or scientific forms.
What is the difference between a US ton and a metric ton?
A US short ton is 2,000 lb (about 907.185 kg). A metric ton is exactly 1,000 kg (about 2,204.623 lb). The metric ton is roughly 10.2% heavier. A long ton - used in British shipping - is 2,240 lb and sits between the two, but this converter uses the US short ton.
Where are ounces and pounds used?
Ounces and pounds are the everyday weight units in the US for food labels, body weight, and shipping. The UK uses pounds and stones for personal weight but kilograms in most other contexts. Nearly every other country uses grams, kilograms, and metric tons as the default.
How many ounces are in a pound?
1 pound contains exactly 16 avoirdupois ounces, so 1 oz is about 28.349523 grams. This is the standard ounce for food, luggage, and shipping - not the troy ounce (about 31.1035 g) used for gold and silver.
