Worked examples
Converting 5 US tons
Multiply 5 by 14000000. That gives 70,000,000 grains. A quick sanity check: one US ton is larger than one grain, so the number should get bigger — and it does.
Converting 72 US tons
72 × 14000000 = 1,008,000,000 grains. Working backwards, 1,008,000,000 ÷ 14000000 returns 72 US tons, which confirms the factor is applied the right way round.
