Conversion derivation

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

1. 1

   Rewrite year in the base unit

   $$1\mathrm{year}=31,556,952\mathrm{s}$$
2. 2

   Rewrite ms in the base unit

   $$1\mathrm{ms}=0.001\mathrm{s}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{year}& =\frac{31,556,952\cancel{\mathrm{s}}}{0.001\cancel{\mathrm{s}}}\times 1\mathrm{ms}\\ & =\frac{31,556,952}{0.001}\mathrm{ms}\\ & =3.1556952\times 10^{10}\mathrm{ms}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{ms}& =\frac{0.001\cancel{\mathrm{s}}}{31,556,952\cancel{\mathrm{s}}}\times 1\mathrm{year}\\ & =\frac{0.001}{31,556,952}\mathrm{year}\\ & =3.16887385\times 10^{-11}\mathrm{year}\end{array}$$
