Quick estimate in your head

For a rough answer, multiply by about 30000: 2 × 30000 ≈ 60,000 um, against the exact 50,800 um (18.1% 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 inch is bigger than a micrometer, so the number of micrometers must come out larger than the number of inches. If your answer goes the other way, divide instead of multiplying.
