s vers us convertisseur - Seconde vers Microseconde

Conversion derivation

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

1. 1

   Rewrite s in the base unit

   $$1\mathrm{s}=1\mathrm{s}$$
2. 2

   Rewrite us in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{s}& =\frac{1\cancel{\mathrm{s}}}{0.000001\cancel{\mathrm{s}}}\times 1\mathrm{us}\\ & =\frac{1}{0.000001}\mathrm{us}\\ & =1,000,000\mathrm{us}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{us}& =\frac{0.000001\cancel{\mathrm{s}}}{1\cancel{\mathrm{s}}}\times 1\mathrm{s}\\ & =\frac{0.000001}{1}\mathrm{s}\\ & =0.000001\mathrm{s}\end{array}$$
