h vers min convertisseur - Heure vers Minute

Conversion derivation

Express both h and min in the same base unit s (second), then cancel the shared base unit.

1. 1

   Rewrite h in the base unit

   $$1\mathrm{h}=3,600\mathrm{s}$$
2. 2

   Rewrite min in the base unit

   $$1\min =60\mathrm{s}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{h}& =\frac{3,600\cancel{\mathrm{s}}}{60\cancel{\mathrm{s}}}\times 1\min \\ & =\frac{3,600}{60}\min \\ & =60\min \end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\min & =\frac{60\cancel{\mathrm{s}}}{3,600\cancel{\mathrm{s}}}\times 1\mathrm{h}\\ & =\frac{60}{3,600}\mathrm{h}\\ & =0.016666666667\mathrm{h}\end{array}$$
