Quick estimate in your head
For a rough answer, multiply by about 300000: 300 × 300000 ≈ 90,000,000 um, against the exact 91,440,000 um (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 foot is bigger than a micrometer, so the number of micrometers must come out larger than the number of feet. If your answer goes the other way, divide instead of multiplying.
