Worked examples
Converting 5 teaspoons
Multiply 5 by 4.9289216e-06. That gives 0.000025 cubic meters. A quick sanity check: one teaspoon is smaller than one cubic meter, so the number should get smaller — and it does.
Converting 72 teaspoons
72 × 4.9289216e-06 = 0.000355 cubic meters. Working backwards, 0.000355 ÷ 4.9289216e-06 returns 72 teaspoons, which confirms the factor is applied the right way round.
