Quick estimate in your head
For a rough answer, multiply by about 1000: 400 × 1000 ≈ 400,000 g, against the exact 400,000 g (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 kilogram is bigger than a gram, so the number of grams must come out larger than the number of kilograms. If your answer goes the other way, divide instead of multiplying.
