ppm から umol/L 変換ツール - 百万分の一 から マイクロモル濃度

Conversion derivation

Express both ppm and umol/L in the same base unit mol/L (molar), then cancel the shared base unit.

1. 1

   Rewrite ppm in the base unit

   $$1\mathrm{ppm}=0.000001mol/L$$
2. 2

   Rewrite umol/L in the base unit

   $$1umol/L=0.000001mol/L$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{ppm}& =\frac{0.000001\cancel{mol/L}}{0.000001\cancel{mol/L}}\times 1umol/L\\ & =\frac{0.000001}{0.000001}umol/L\\ & =1umol/L\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1umol/L& =\frac{0.000001\cancel{mol/L}}{0.000001\cancel{mol/L}}\times 1\mathrm{ppm}\\ & =\frac{0.000001}{0.000001}\mathrm{ppm}\\ & =1\mathrm{ppm}\end{array}$$
