About Ounces and Metric tons
Ounces (oz): From the Latin uncia meaning one-twelfth (originally 1/12 of a Roman pound, now 1/16 of an avoirdupois pound); the modern avoirdupois ounce is exactly 28.349523125 grams. Common uses: US cooking, postal weight for letters and small parcels, food packaging in the US, and (as a slightly different troy ounce, 31.10 g) the standard unit for precious metals worldwide.
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).
