Quick estimate in your head

For a rough answer, multiply by about 2000000000: 250 × 2000000000 ≈ 500,000,000,000 um, against the exact 463,000,000,000 um (8.0% 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 nautical mile is bigger than a micrometer, so the number of micrometers must come out larger than the number of nautical miles. If your answer goes the other way, divide instead of multiplying.
