About Kilograms and Metric tons
Kilograms (kg): The SI base unit of mass; defined since 2019 by the Planck constant, replacing a physical platinum-iridium artifact (Le Grand K) that had served as the definition for 130 years. Common uses: Body weight (everywhere except the US), shipping and freight, food packaging, athletics (Olympic lifts, international powerlifting), and any large-scale industrial measurement.
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 kilogram and metric ton.
The exact relationship is metric tons = kilograms × 0.001, 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 kilograms 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.
