pounds = kilograms ÷ 0.45359237kilograms = pounds × 0.45359237Pounds and ounces
A pound has 16 ounces, so decimal pounds are often rewritten as pounds and ounces: 7.716 lb is 7 lb 11.5 oz. Baby weights, fish and parcels are usually given this way in the United States, and the result shows both forms.
Grams and ounces
One ounce is exactly 28.349523125 grams. Kitchen scales and recipes often round it to 28 grams, which is also the value used on U.S. nutrition labels. For small amounts, grams are more precise than fractions of an ounce.
Stones
A stone is 14 pounds, about 6.35 kilograms. It is still used for body weight in the United Kingdom and Ireland, so 11 st 4 lb means 158 pounds.
US tons and metric tons
A US ton, also called a short ton, is 2,000 pounds or about 907.2 kilograms. A metric ton, or tonne, is 1,000 kilograms, about 2,204.6 pounds. The British long ton of 2,240 pounds is not included here.
Weight and mass
In everyday use, weight and mass are treated as the same thing, and scales display mass in pounds or kilograms. In physics, weight is the force of gravity on a mass and is measured in newtons; the Weight Calculator handles that force.
