# Convert Milligram to Ton (metric)

Please provide values below to convert milligram [mg] to ton (metric) [t], or *vice versa*.

### Milligram

**Definition:** A milligram is a unit of weight and mass that is based on the SI (International System of Units) base unit of mass, the kilogram. It is equal to 1/1,000 grams, or 1/1,000,000 kilograms.

**History/origin:** The milligram is based on the SI unit of weight and mass, the kilogram. As an SI unit, it uses the "milli" SI prefix to denote that it is a submultiple of the base unit. Although the "milli" prefix denotes a submultiple with respect to the gram, the kilogram, not the gram, is technically the SI base unit of mass.

**Current use:** As a submultiple of an SI base unit, the milligram is widely used in many applications, from everyday use to measure the weight or mass of foods, substances, etc., to widespread use in scientific labs, among other areas.

### Ton

**Definition:** A ton is a unit of weight and mass. In the United States and Canada, the ton, also known as the short ton, is defined as 2,000 pounds, or 908 kilograms. In the United Kingdom, the ton, sometimes referred to as the long ton, is defined as 2,240 avoirdupois pounds, or 1,016 kg. The tonne, defined in the International System of Units (SI) and also known as the metric ton is defined as 2,204.623 pounds, or 1,000 kilograms.

**History/origin:** The term "ton" is derived from the "tun," a term that was applied to a large cask that could contain between 175 to 213 imperial gallons, could weigh around 2,000 pounds, and could occupy approximately 60 cubic feet, or 1.7 m^{3} of space. Although various definitions of the ton are still used in certain countries, the metric ton, or tonne, is the preferred definition of the ton.

**Current use:** The long ton is used in the United Kingdom along with other countries that still use the imperial system, the short ton is used mainly in the United States, and the tonne is used worldwide. Although both the UK, the US, and some other countries still use other definitions of the ton, the tonne is the legally designated form of the ton for use in trade.
