An unabridged dictionary, a medium cantaloupe and a bottle of wine all weigh approximately 1 kilogram. Other 1-kilogram objects include a liter of water, a pineapple and a small laptop.

Kilograms are part of the metric system, which is the standard of measurement in most of the world. Other common mass measures in the metric system are grams and tonnes, which are also known as metric tons. Some examples of 1 gram objects are a paper clip and a coat button. One thousand grams are equivalent to 1 kilogram. A large motorcycle has a mass of approximately 250 kilograms. Tonnes differ from tons and short tons, which are units of weight based on the pound.

One kilogram is equal to about 2.2 pounds. Although both kilograms and pounds are measured with a scale, kilograms are a measure of mass, or the amount of matter in an object. Pounds are a measure of weight, which is the force of gravity on an object. The mass of an object does not change, while weight is affected by fluctuations in gravity. A 1 kg object on Earth has the same mass but a different weight if it is taken to the Moon.
