Quick estimate in your head
For a rough answer, multiply by about 0.00004: 12 × 0.00004 ≈ 0.00048 in, against the exact 0.00047244 in (1.6% 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 micrometer is smaller than a inch, so the number of inches must come out smaller than the number of micrometers. If your answer goes the other way, divide instead of multiplying.
