Torr vers mbar convertisseur - Torr vers Millibar

Conversion derivation

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

1. 1

   Rewrite Torr in the base unit

   $$1\mathrm{Torr}=133.322\mathrm{Pa}$$
2. 2

   Rewrite mbar in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Torr}& =\frac{133.322\cancel{\mathrm{Pa}}}{100\cancel{\mathrm{Pa}}}\times 1\mathrm{mbar}\\ & =\frac{133.322}{100}\mathrm{mbar}\\ & =1.33322\mathrm{mbar}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mbar}& =\frac{100\cancel{\mathrm{Pa}}}{133.322\cancel{\mathrm{Pa}}}\times 1\mathrm{Torr}\\ & =\frac{100}{133.322}\mathrm{Torr}\\ & =0.750063755419\mathrm{Torr}\end{array}$$
