A paperclip weighs about a gram, therefore many items are measured in hundreds or thousands of grams. For larger, more massive items over 1,000 grams, a kilogram measurement is used. One kilogram equals 1,000 grams. Most scales use the metric system and report the weights of larger items, such as animals and humans, in kilograms. For example, a doctor weighs a patient in kilograms.
