About Grams and Metric tons
Grams (g): Originally defined in 1795 as the mass of one cubic centimeter of water at 4°C; now defined as one thousandth of a kilogram, with the kilogram defined since 2019 by the Planck constant. Common uses: Cooking (especially baking), nutrition labels, postal weight for small parcels, jewelry, and almost any precise mass measurement outside the United States.
Metric tons (t): One thousand kilograms, a metric-system unit standardized in the early 19th century; called a 'tonne' in international SI usage, 'metric ton' in US usage. Common uses: Shipping and freight, industrial commodities (steel, grain, cement), large-scale manufacturing, and emissions accounting (carbon dioxide emissions are reported in metric tons).
How the conversion works
Mass conversions use the SI definition: 1 pound is exactly 0.45359237 kilograms. The factor above is the exact ratio between gram and metric ton.
The exact relationship is metric tons = grams × 0.000001, which the calculator at the top of this page applies in both directions. Type into either field and the other updates immediately.
When this conversion matters
Converting between grams and metric tons comes up wherever weight & mass measurements move between systems — from one country's conventions to another's, from a scientific reference to a practical specification, or from one industry's working unit to another's. The calculator and reference table above cover the everyday range; for unusual values you can type any number into either field.
