psi vers mmHg convertisseur - Livres par Pouce Carré vers Millimètres de Mercure

Conversion derivation

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

1. 1

   Rewrite psi in the base unit

   $$1\mathrm{psi}=6,894.76\mathrm{Pa}$$
2. 2

   Rewrite mmHg in the base unit

   $$1\mathrm{mmHg}=133.322\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{psi}& =\frac{6,894.76\cancel{\mathrm{Pa}}}{133.322\cancel{\mathrm{Pa}}}\times 1\mathrm{mmHg}\\ & =\frac{6,894.76}{133.322}\mathrm{mmHg}\\ & =51.7150957831\mathrm{mmHg}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mmHg}& =\frac{133.322\cancel{\mathrm{Pa}}}{6,894.76\cancel{\mathrm{Pa}}}\times 1\mathrm{psi}\\ & =\frac{133.322}{6,894.76}\mathrm{psi}\\ & =0.019336713678\mathrm{psi}\end{array}$$
