톤 (ton) is a unit of measurement used to quantify weight. In the metric system, one ton is equivalent to 1,000 kilograms. There are different types of tons, including the metric ton, which is commonly used in most countries, and the imperial ton, also known as the long ton, which is used in the United Kingdom and is equal to 1,016 kilograms. In addition to weight, the term "톤" can also refer to the tone of voice or sound in music. In this context, it describes the quality or character of a sound, which can be influenced by factors such as pitch, volume, and timbre. Understanding tone is essential in fields like music and communication.
