h vers us convertisseur - Heure vers Microseconde

Conversion derivation

Express both h and us 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 us in the base unit

   $$1\mathrm{us}=0.000001\mathrm{s}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{h}& =\frac{3,600\cancel{\mathrm{s}}}{0.000001\cancel{\mathrm{s}}}\times 1\mathrm{us}\\ & =\frac{3,600}{0.000001}\mathrm{us}\\ & =3.6\times 10^9\mathrm{us}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{us}& =\frac{0.000001\cancel{\mathrm{s}}}{3,600\cancel{\mathrm{s}}}\times 1\mathrm{h}\\ & =\frac{0.000001}{3,600}\mathrm{h}\\ & =2.77777778\times 10^{-10}\mathrm{h}\end{array}$$
