Convert Metric Ton to US Ton (t → ton (US))

Converting metric tons to US tons is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.

1. 1
   Take your value in metric tons

   Start with the number of metric tons (t) you want to convert.
2. 2
   Multiply by 1.102311

   The conversion factor from t to ton (US) is 1.102311. Multiply your value by this number.
3. 3
   Read the result in US tons

   The result is your value in US tons (ton (US)).

Multiply the value in metric tons by 1.102311. For the reverse direction, multiply by 0.907185.

• ✓1 t = 1000 kg exactly. The British "tonne" and the metric "ton" are identical.
• ✓In export contracts always specify "metric ton" or "MT" to avoid ambiguity with US or UK tons.
• ✓Commodity prices (wheat, sugar, iron ore) are usually quoted per metric ton.

• ✗Using "ton" without qualifier in US contracts — default is often the short ton (907 kg), a 9% gap.
• ✗Confusing metric ton with long ton on UK-origin commodity contracts.
• ✗Writing "ton" when accuracy matters in shipping — always write "MT" or "tonne".

What is the Metric Ton?

The metric ton (or tonne) equals exactly 1,000 kilograms and is the international standard for shipping, agriculture, construction, and industrial weight. Adopted as part of the SI system, the metric ton is used worldwide for bulk commodities (grain harvests measured in tons per hectare), vehicle and shipping container masses, freight rates, and CO₂ emissions accounting. A standard 20-foot shipping container has a maximum gross weight of about 24 metric tons. The metric ton is distinct from the US short ton (907.185 kg) and the UK long ton (1,016.047 kg). The unit's spelling differs by country — 'tonne' in British and international usage, 'metric ton' in American — but the abbreviation 't' is universal. It relates to the kilogram (1,000 kg = 1 t) and the megagram (1 Mg = 1 t).

• Agricultural yield (grain, sugar, coffee)
• Steel, cement and industrial production

What is the US Ton?

The US short ton equals exactly 2,000 pounds or 907.18474 kilograms, and is the standard weight unit for American freight, mining, construction, and waste management. Its name distinguishes it from the longer UK long ton (2,240 lb). The short ton emerged in the United States during the 19th century to simplify calculations: 2,000 is a rounder number than 2,240. Today it dominates American industry — coal mining quotes production in short tons, dump trucks are rated by short-ton capacity, and the EPA tracks emissions in short tons. Imperial-to-metric confusion can be costly: in 1999, the Mars Climate Orbiter spacecraft was lost partly due to a units mismatch involving pounds and newtons. The short ton relates to the pound (2,000 lb = 1 ton), the metric ton (1 short ton ≈ 0.907 t), and the long ton (1 long ton = 1.12 short tons).
