1 Ton = 1 Megagram ;D
1 Ton = 1 Megagram ;D
We were actually thinking about megagram and also megameter. But the world isn't ready.
The point is that 'ton' is ambiguous.
Long ton A unit of mass in the Imperial system that is equal to 2,240 pounds. It is also known as the British ton.
Short ton A unit of mass in the avoirdupois system that is equal to 2,000 pounds. It is also known as the US ton.
All systems but the metric one were long forgotten in the Factorio universe, so I don't see any ambiguity.
