Pounds, Ounces and Stones
The pound is used for body weight, groceries and shipping in the United States, and 1 pound is 16 ounces. In the UK and Ireland, body weight is often given in stones and pounds, where 1 stone is 14 pounds. A person who weighs 70 kg is 154.3 lb, which is 11 st 0.3 lb. If you track your weight, the BMI calculator accepts both metric and US units, and the ideal weight calculator gives a healthy range for your height.
Metric Tons, US Tons and UK Tons
The word ton means different things. A metric ton, also called a tonne, is 1,000 kg. The US short ton is 2,000 pounds and the UK long ton is 2,240 pounds, so the three differ by several percent. Check which one a freight or material quote uses before converting.
| Ton | Equals | In kilograms |
|---|---|---|
| Metric ton (tonne) | 1,000 kg | 1,000 |
| US ton (short ton) | 2,000 lb | 907.18474 |
| UK ton (long ton) | 2,240 lb | 1,016.0469 |
Cooking, Gold and Everyday Weights
Recipes often switch between grams and ounces, and 100 g is about 3.53 oz. Gold, silver and other precious metals are priced in troy ounces, which equal 31.1034768 grams, about 10 percent more than a regular ounce. Gemstones use the carat, and 1 carat is exactly 0.2 grams. For amounts of liquid use the volume converter, and for distances see the length converter or the temperature converter, or the main unit converter for every category in one place.
Weight vs Mass
Mass is how much matter an object has, while weight is the force of gravity pulling on it. A kilogram of flour has the same mass on Earth and on the Moon, but it weighs less on the Moon. The newton option shows that force at standard gravity, where 1 kg of mass weighs 9.80665 N.
