About Milligrams and Metric tons
Milligrams (mg): One thousandth of a gram, used since the metric system was formalized in France in 1799. Common uses: Pharmaceutical dosing (drug tablets, vitamins, supplements), nutrition labels for small quantities, and chemistry.
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
