An example of an object that weighs 1 kilogram is a large book, such as a dictionary. A kilogram is a metric unit used to measure the amount of mass in an object. One kilogram is roughly equal to 2.2 pounds. Additional examples of items that weigh roughly 1 kilogram include a bag of rice, a liter of water or a professional digital camera.
In the metric system, the gram is the unit of measure. However, a single gram weighs little. A paperclip weighs about 1 gram. Accordingly, to make things easier, the metric system uses a variety of prefixes that can be added to the term “gram” to make a different unit of measure. For example, a kilogram is equal to 1,000 grams.
In the United States, the units of measure most often used are called the imperial units. The pound is the imperial unit for weight. However, in most other countries, the metric system prevails, and the gram or kilogram is the primary unit of measure for weight or mass. One gram is equal to about .035 ounces; in other words, there are approximately 28.35 grams per ounce. An archaic unit of measure, called 1 stone, weighs about 6.35 kilograms.
