Quick estimate in your head

For a rough answer, multiply by about 0.0005: 100 × 0.0005 ≈ 0.05 ton, against the exact 0.05 ton (0.0% out). Good enough to check that a calculated result is sensible.

Common mistakes

The usual slip is using the factor the wrong way round. A pound is smaller than a US ton, so the number of US tons must come out smaller than the number of pounds. If your answer goes the other way, divide instead of multiplying.
