Unit definitions

Pascal

The pascal is the SI unit of pressure. It is defined as one newton per square meter.

Millimeters of mercury

mmHg is the global standard for measuring blood pressure. $P = \rho \cdot g \cdot h$ can be used to calculate the hydrostatic pressure exerted by a fluid. $$P = \rho \cdot g \cdot h$$ $\rho \approx 13\,595.1\ \text{kg/m}^3$ at $0^\circ\text{C}$ $$g = 9.806\,65\ \text{m/s}^2$$ $$h = 0.001\ \text{m}$$ $$1\ \text{mmHg} \approx 133.322\ \text{Pa}$$

How to convert Pascal to Millimeters of mercury

$$\text{Pressure}_{\text{mmHg}} = \text{Pressure}_{\text{Pa}} \cdot 0.007500616827041697508018751542067604$$

Examples

Example 1

Convert $50.0\ \text{Pa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 50.0 \cdot 0.007500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 0.375031$$

$$\therefore \ 50.0\ \text{Pa} = 0.375031 \ \text{mmHg}$$

Example 2

Convert $75.0\ \text{Pa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 75.0 \cdot 0.007500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 0.562546$$

$$\therefore \ 75.0\ \text{Pa} = 0.562546 \ \text{mmHg}$$

Example 3

Convert $115.0\ \text{Pa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 115.0 \cdot 0.007500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 0.862571$$

$$\therefore \ 115.0\ \text{Pa} = 0.862571 \ \text{mmHg}$$

Example 4

Convert $145.0\ \text{Pa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 145.0 \cdot 0.007500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 1.087589$$

$$\therefore \ 145.0\ \text{Pa} = 1.087589 \ \text{mmHg}$$

Example 5

Convert $165.0\ \text{Pa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 165.0 \cdot 0.007500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 1.237602$$

$$\therefore \ 165.0\ \text{Pa} = 1.237602 \ \text{mmHg}$$
