Worked examples
Converting 5 decimeters
Multiply 5 by 6.2137119e-05. That gives 0.000311 miles. A quick sanity check: one decimeter is smaller than one mile, so the number should get smaller — and it does.
Converting 72 decimeters
72 × 6.2137119e-05 = 0.004474 miles. Working backwards, 0.004474 ÷ 6.2137119e-05 returns 72 decimeters, which confirms the factor is applied the right way round.
