1 ounce (oz) equals exactly 2.8350e-05 metric tons (t). Use the formula: oz × 2.8350e-05 = t.
To convert ounces to metric tons, multiply your value in ounces by 2.8350e-05. For example, 5 oz × 2.8350e-05 = 0.00014175 t.
100 ounces = 0.00283495 metric tons. Calculation: 100 × 2.8350e-05 = 0.00283495.
To convert metric tons back to ounces, divide by 2.8350e-05 (or multiply by 35273.9907). Example: 10 t ÷ 2.8350e-05 = 352739.9072 oz.
Yes. This converter uses the internationally recognised exact conversion factor: 1 oz = 2.8350e-05 t. All calculations are performed in your browser with no rounding until display.
10 ounces = 0.00028349 metric tons. Simply multiply by 2.8350e-05.
Converting ounces to metric tons is commonly needed for freight logistics, commodity trading, construction material procurement, and agricultural reporting where one system uses oz and another uses t.
The avoirdupois ounce (oz) equals exactly 28.349523125 grams or 1/16 of an avoirdupois pound. It is widely used in the US and UK for food portions, product packaging, and everyday measurements. Note that the troy ounce (31.1035 g), used for precious metals like gold and silver, is a different and heavier unit than the avoirdupois ounce.
The metric ton (tonne, symbol t) equals exactly 1,000 kilograms or 1,000,000 grams. Not an SI unit but derived from the kilogram, it is used globally for large-scale measurements in shipping, agriculture, mining, and manufacturing. In the US, "metric ton" or "tonne" distinguishes it from the US short ton (2,000 lb ≈ 907 kg) and UK long ton (2,240 lb ≈ 1,016 kg).
The word "ounce" derives from Latin uncia (a twelfth), originally 1/12 of the Roman pound. The avoirdupois ounce developed in medieval England specifically for the wool trade, creating a 16-ounce pound distinct from the Troy 12-ounce pound. The British Imperial system codified the ounce in 1824. The modern exact definition (28.349523125 g) was set by the 1959 International Yard and Pound Agreement.
Interesting fact: A troy ounce (31.1 g) used for gold is heavier than an avoirdupois ounce (28.35 g) used for food — so an "ounce" of gold contains more metal than an "ounce" of flour. A standard large hen's egg weighs approximately 56–63 grams (about 2 oz).
The tonne was introduced alongside the metric system in late 18th-century France and incorporated into the International System as an accepted non-SI unit. Its name (with final "e") was adopted to avoid confusion with British and American ton units. As international trade standardised on metric units through the 20th century, the metric ton became the global benchmark for commodity markets in grain, oil, steel, and other bulk goods.
Interesting fact: A standard ISO shipping container (20-foot TEU) can carry approximately 21–24 metric tons of cargo. The global annual steel production is about 1.9 billion metric tons — roughly 240 kg for every person on Earth.
