psi vers bar convertisseur - Livres par Pouce Carré vers Bar

Conversion derivation

Express both psi and bar 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 bar in the base unit

   $$1\mathrm{bar}=100,000\mathrm{Pa}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{psi}& =\frac{6,894.76\cancel{\mathrm{Pa}}}{100,000\cancel{\mathrm{Pa}}}\times 1\mathrm{bar}\\ & =\frac{6,894.76}{100,000}\mathrm{bar}\\ & =0.0689476\mathrm{bar}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{bar}& =\frac{100,000\cancel{\mathrm{Pa}}}{6,894.76\cancel{\mathrm{Pa}}}\times 1\mathrm{psi}\\ & =\frac{100,000}{6,894.76}\mathrm{psi}\\ & =14.5037680789\mathrm{psi}\end{array}$$
