Quick estimate in your head

For a rough answer, multiply by about 600000: 3 × 600000 ≈ 1,800,000 s, against the exact 1,814,400 s (0.8% 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 week is bigger than a second, so the number of seconds must come out larger than the number of weeks. If your answer goes the other way, divide instead of multiplying.
