nm a A convertitore - Nanometro a Ångström

Conversion derivation

Express both nm and A in the same base unit m (meter), then cancel the shared base unit.

1. 1

   Rewrite nm in the base unit

   $$1\mathrm{nm}=1\times 10^{-9}\mathrm{m}$$
2. 2

   Rewrite A in the base unit

   $$1\mathrm{A}=1\times 10^{-10}\mathrm{m}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{nm}& =\frac{1\times 10^{-9}\cancel{\mathrm{m}}}{1\times 10^{-10}\cancel{\mathrm{m}}}\times 1\mathrm{A}\\ & =\frac{1\times 10^{-9}}{1\times 10^{-10}}\mathrm{A}\\ & =10\mathrm{A}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{A}& =\frac{1\times 10^{-10}\cancel{\mathrm{m}}}{1\times 10^{-9}\cancel{\mathrm{m}}}\times 1\mathrm{nm}\\ & =\frac{1\times 10^{-10}}{1\times 10^{-9}}\mathrm{nm}\\ & =0.1\mathrm{nm}\end{array}$$
