1 g = 1.0000 × 10^−6 t (gram → metric ton)
1 g = 1.0000 × 10^−6 t
1 gram equals 1.0000 × 10^−6 metric tons. To convert grams to metric tons, multiply the gram value by 1.0000 × 10^−6. For quick reference: 1 g = 1.0000 × 10^−6 t, 5 g = 5.0000 × 10^−6 t, 10 g = 1.0000 × 10^−5 t, 100 g = 0.0001 t.
Metric tons = Grams × 1.0000 × 10^−6Grams to metric tonnes divides by 1 000 000 — a six-zero decimal shift (1 t = 1000 kg = 1 000 000 g). A 500 g package is 0.0005 t; a shipment of 2 500 000 g of grain is 2.5 t. The conversion appears when per-item gram weights from a product database get aggregated into freight-scale totals. Track the zeros in a spreadsheet carefully: dropping one turns a 25 t container load into a 2.5 t entry, an error big enough to invalidate a shipping manifest.
Laboratory reagent inventories and precious-metal assay reports occasionally need this jump because purchasing systems track bulk chemicals in tonnes while the bench technician weighs out grams. 500 g of a reagent is 0.0005 t; a 250,000 g drum is 0.25 t; 3,000,000 g of processed ore concentrate is 3 t. Because the ratio is a straight million, it's easier to shift the decimal point six places than to multiply — reserve a calculator for cross-checking, not for doing the conversion itself.
Start with your value in grams.
Multiply the gram value by 1.0000 × 10^−6. This is the exact conversion factor from grams to metric tons.
The product is your value in metric tons. For example, 5 g × 1.0000 × 10^−6 = 5.0000 × 10^−6 t.
The exact factor from grams to metric tons is 1.0000 × 10^−6.

A standard paperclip is about 1 g. A US nickel weighs 5 g. A small pencil weighs around 7 g.
The gram (g) is a metric unit of mass equal to one-thousandth of a kilogram. It is the everyday unit for food labeling, postage, jewelry, and laboratory measurements. The 2019 SI redefinition fixed the kilogram (and therefore the gram) in terms of Planck's constant, ending more than a century of dependence on a physical prototype.
The metric ton, or tonne (t), equals exactly 1,000 kilograms. It is the standard unit for industrial shipping, freight, and bulk commodities such as steel, grain, and cement. Despite the name, it is not part of the strict SI system (the SI name is the megagram), but it is universally accepted in commerce and engineering.
