psi a MPa convertidor - Libra por pulgada cuadrada a Megapascal

Conversion derivation

Express both psi and MPa 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 MPa in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{psi}& =\frac{6,894.76\cancel{\mathrm{Pa}}}{1,000,000\cancel{\mathrm{Pa}}}\times 1\mathrm{MPa}\\ & =\frac{6,894.76}{1,000,000}\mathrm{MPa}\\ & =0.00689476\mathrm{MPa}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{MPa}& =\frac{1,000,000\cancel{\mathrm{Pa}}}{6,894.76\cancel{\mathrm{Pa}}}\times 1\mathrm{psi}\\ & =\frac{1,000,000}{6,894.76}\mathrm{psi}\\ & =145.037680789\mathrm{psi}\end{array}$$
