Kilograms (kg) to Tons Converter (Metric, US Short, UK Long)
Convert kg to Metric Tonnes, US Short Tons, and UK Long Tons simultaneously. Critical for international logistics, shipping, and trade agreements.
About
In international trade and heavy industry, the word "ton" is dangerously ambiguous. A contract specifying "100 tons" represents significantly different masses depending on whether it implies the Metric Tonne (t), the US Short Ton (ST), or the Imperial/UK Long Ton (LT). Using the wrong unit can lead to expensive logistics errors or safety hazards. This tool calculates all three variations simultaneously from a Kilogram (kg) input, providing clarity for shipping manifests and engineering loads.

Formulas
The conversion factors are distinct for each system:
m(t) = m(kg)1000
m(ST) = m(kg) × 0.00110231
m(LT) = m(kg) × 0.00098421

Frequently Asked Questions
A Metric Tonne is exactly 1000 kg. A US Short Ton is 2000 lbs (approx. 907 kg). A UK Long Ton is 2240 lbs (approx. 1016 kg). The Metric Tonne is the standard for international trade.
Maritime shipping often uses the Metric Tonne (MT) or Long Ton (LT) depending on the vessel's registration and route. Road transport in the US exclusively uses Short Tons.
Use the symbol "t" or "MT". Avoid capitalizing "Ton" without a prefix, as it implies the Short Ton in the US and the Long Ton in the UK.
