mmHg vers Pa convertisseur - Millimètres de Mercure vers Pascal

Conversion derivation

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

1. 1

   Rewrite mmHg in the base unit

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

   Rewrite Pa in the base unit

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

   Forward conversion

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

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{Pa}& =\frac{1\cancel{\mathrm{Pa}}}{133.322\cancel{\mathrm{Pa}}}\times 1\mathrm{mmHg}\\ & =\frac{1}{133.322}\mathrm{mmHg}\\ & =0.007500637554\mathrm{mmHg}\end{array}$$
