bar vers mbar convertisseur - Bar vers Millibar

Conversion derivation

Express both bar and mbar in the same base unit Pa (pascal), then cancel the shared base unit.

1. 1

   Rewrite bar in the base unit

   $$1\mathrm{bar}=100,000\mathrm{Pa}$$
2. 2

   Rewrite mbar in the base unit

   $$1\mathrm{mbar}=100\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{bar}& =\frac{100,000\cancel{\mathrm{Pa}}}{100\cancel{\mathrm{Pa}}}\times 1\mathrm{mbar}\\ & =\frac{100,000}{100}\mathrm{mbar}\\ & =1,000\mathrm{mbar}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mbar}& =\frac{100\cancel{\mathrm{Pa}}}{100,000\cancel{\mathrm{Pa}}}\times 1\mathrm{bar}\\ & =\frac{100}{100,000}\mathrm{bar}\\ & =0.001\mathrm{bar}\end{array}$$
