Pa vers bar convertisseur - Pascal vers Bar

Conversion derivation

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

1. 1

   Rewrite Pa in the base unit

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

   Rewrite bar in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{Pa}& =\frac{1\cancel{\mathrm{Pa}}}{100,000\cancel{\mathrm{Pa}}}\times 1\mathrm{bar}\\ & =\frac{1}{100,000}\mathrm{bar}\\ & =0.00001\mathrm{bar}\end{array}$$
4. 4

   Reverse conversion

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