atm in mmHg Umrechner - Standardatmosphäre in Millimeter Quecksilbersäule

Conversion derivation

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

1. 1

   Rewrite atm in the base unit

   $$1\mathrm{atm}=101,325\mathrm{Pa}$$
2. 2

   Rewrite mmHg in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{atm}& =\frac{101,325\cancel{\mathrm{Pa}}}{133.322\cancel{\mathrm{Pa}}}\times 1\mathrm{mmHg}\\ & =\frac{101,325}{133.322}\mathrm{mmHg}\\ & =760.002100179\mathrm{mmHg}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mmHg}& =\frac{133.322\cancel{\mathrm{Pa}}}{101,325\cancel{\mathrm{Pa}}}\times 1\mathrm{atm}\\ & =\frac{133.322}{101,325}\mathrm{atm}\\ & =0.001315785838\mathrm{atm}\end{array}$$
