Quick estimate in your head

For a rough answer, multiply by about 0.001: 30 × 0.001 ≈ 0.03 kg, against the exact 0.03 kg (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 gram is smaller than a kilogram, so the number of kilograms must come out smaller than the number of grams. If your answer goes the other way, divide instead of multiplying.
