Convert Gram to Ton (metric)

Please provide values below to convert gram [g] to ton (metric) [t], or vice versa.



Definition: A gram (symbol: g) is a unit of mass in the International System of Units (SI). The definition of the gram is based on the kilogram, where a gram is one thousandth of a kilogram, the SI base unit of mass. Since 2019, the definition of the kilogram is no longer based on the international prototype, and rather is based on Planck's constant, h, along with the new definitions of the second and the meter.

History/origin: Originally, a gram was defined as the absolute weight of pure water in a cubic centimeter at the temperature of melting ice (later 4 °C). The gram used to be a fundamental unit of mass as part of centimeter-gram-second systems of units up until the widespread adoption of SI, which uses kilograms as the base unit of mass. The gram was later redefined as one thousandth of a kilogram, the SI (meter-kilogram-second system of units) base unit of mass.

Current use: The gram is widely used in every life as well as scientific contexts. For example, the gram is typically used to measure non-liquid ingredients used for cooking or groceries. Standards on the nutrition labels of food products often require the relative contents to be stated per 100 grams of the product.


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 m3 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.

How to Convert Gram to Ton (metric)

1 g = 1.0E-6 t
1 t = 1000000 g

Example: convert 15 g to t:
15 g = 15 × 1.0E-6 t = 1.5E-5 t
