What is a hundredweight?
A hundredweight, abbreviated as cwt, is a unit of weight commonly used in the imperial system of measurement.
There are two variations on hundredweights; the long hundredweight primarily used in the United Kingdom and the short hundredweight used in the United States.
In the imperial system, a long hundredweight is equal to 112 pounds or approximately 50.8 kilograms. The term "hundredweight" is derived from the fact that it originally represented the weight of 100 pounds of a particular commodity.
The short hundredweight is equal to 100 pounds or 45.35 kilograms.
What is a kilogram?
A kilogram is metric unit of weight subdivided into 1,000 grams. The base unit of mass in the International System of Units (SI) is a kilogram and not, as is quite often mistaken, the gram.
One liter of water weighs 1kg.
