mbar vers MPa convertisseur - Millibar vers Mégapascal

Conversion derivation

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

1. 1

   Rewrite mbar in the base unit

   $$1\mathrm{mbar}=100\mathrm{Pa}$$
2. 2

   Rewrite MPa in the base unit

   $$1\mathrm{MPa}=1,000,000\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{mbar}& =\frac{100\cancel{\mathrm{Pa}}}{1,000,000\cancel{\mathrm{Pa}}}\times 1\mathrm{MPa}\\ & =\frac{100}{1,000,000}\mathrm{MPa}\\ & =0.0001\mathrm{MPa}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{MPa}& =\frac{1,000,000\cancel{\mathrm{Pa}}}{100\cancel{\mathrm{Pa}}}\times 1\mathrm{mbar}\\ & =\frac{1,000,000}{100}\mathrm{mbar}\\ & =10,000\mathrm{mbar}\end{array}$$
