Convert Metric Tons to Stones

About converting Metric Tons to Stones

Metric Tons (t) and Stones (st) are both units of weight & mass, so converting between them is a single multiplication: multiply your Metric Tons figure by 157.473. Ten Metric Tons comes to 1,574.73 Stones, and a hundred works out at 15,747.3 Stones.

Rule of thumb: going from Metric Tons to Stones multiplies, so the figure always grows — one Metric Ton is already 157.473 Stones. If your answer came out smaller, you have the conversion the wrong way round.

What is a Metric Ton?

A metric ton — spelled tonne almost everywhere outside the United States — is 1,000 kilograms. It is not strictly an SI unit, though SI accepts it for use alongside them; the coherent name would be the megagram, which essentially nobody says out loud. The real hazard is the bare word "ton", because a US short ton of 2,000 pounds and a British long ton of 2,240 pounds are different quantities again, and all three are close enough that a careless figure can pass unchallenged. It is the unit of freight, steel, harvests and carbon dioxide emissions.

What is a Stone?

The stone is fourteen pounds and, outside Britain and Ireland, essentially extinct. There it is still how people state body weight: a Briton says "eleven stone four", meaning eleven stone plus four pounds, and the plural stays stone in that construction — never "eleven stones". Americans give the identical weight as a single number in pounds, which is why British figures baffle them. The unit predates standardisation and was once a moving target, with a stone of wool, cheese or glass all weighing different amounts, and it is no longer permitted for trade in the UK at all.

To put both in perspective: a small car weighs about 1.5 metric tons, while most adults weigh somewhere between 9 and 14 stone.
