s 에서 year 변환기 - 초 에서 년

Conversion derivation

Express both s and year 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 year in the base unit

   $$1\mathrm{year}=31,556,952\mathrm{s}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{s}& =\frac{1\cancel{\mathrm{s}}}{31,556,952\cancel{\mathrm{s}}}\times 1\mathrm{year}\\ & =\frac{1}{31,556,952}\mathrm{year}\\ & =3.16887385\times 10^{-8}\mathrm{year}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{year}& =\frac{31,556,952\cancel{\mathrm{s}}}{1\cancel{\mathrm{s}}}\times 1\mathrm{s}\\ & =\frac{31,556,952}{1}\mathrm{s}\\ & =31,556,952\mathrm{s}\end{array}$$
