There are 1,000 kilograms (kg) in 1 ton. The metric ton, often simply referred to as a ton, is a unit of mass in the metric system and is equal to 1,000 kilograms. In some contexts, you may encounter different types of tons, such as the long ton (used in the UK) or the short ton (used in the United States), which are equivalent to approximately 1,016 kilograms and 907 kilograms, respectively. However, the term “ton” without a modifier typically refers to the metric ton in most countries.
