Unit definitions

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 $0^\circ\text{C}$ $$g = 9.806\,65\ \text{m/s}^2$$ $$h = 0.001\ \text{m}$$ $$1\ \text{mmHg} \approx 133.322\ \text{Pa}$$

Pascal

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

How to convert Millimeters of mercury to Pascal

$$\text{Pressure}_{\text{Pa}} = \text{Pressure}_{\text{mmHg}} \cdot 133.3223684210526315789473684210526$$

Examples

Example 1

Convert $20.0\ \text{mmHg}$ to $\text{Pa}$.

$$\text{Pressure}_{\text{Pa}} = 20.0 \cdot 133.3223684210526315789473684210526$$

$$\text{Pressure}_{\text{Pa}} = 2666.447368$$

$$\therefore \ 20.0\ \text{mmHg} = 2666.447368 \ \text{Pa}$$

Example 2

Convert $90.0\ \text{mmHg}$ to $\text{Pa}$.

$$\text{Pressure}_{\text{Pa}} = 90.0 \cdot 133.3223684210526315789473684210526$$

$$\text{Pressure}_{\text{Pa}} = 11999.013158$$

$$\therefore \ 90.0\ \text{mmHg} = 11999.013158 \ \text{Pa}$$

Example 3

Convert $105.0\ \text{mmHg}$ to $\text{Pa}$.

$$\text{Pressure}_{\text{Pa}} = 105.0 \cdot 133.3223684210526315789473684210526$$

$$\text{Pressure}_{\text{Pa}} = 13998.848684$$

$$\therefore \ 105.0\ \text{mmHg} = 13998.848684 \ \text{Pa}$$

Example 4

Convert $135.0\ \text{mmHg}$ to $\text{Pa}$.

$$\text{Pressure}_{\text{Pa}} = 135.0 \cdot 133.3223684210526315789473684210526$$

$$\text{Pressure}_{\text{Pa}} = 17998.519737$$

$$\therefore \ 135.0\ \text{mmHg} = 17998.519737 \ \text{Pa}$$

Example 5

Convert $170.0\ \text{mmHg}$ to $\text{Pa}$.

$$\text{Pressure}_{\text{Pa}} = 170.0 \cdot 133.3223684210526315789473684210526$$

$$\text{Pressure}_{\text{Pa}} = 22664.802632$$

$$\therefore \ 170.0\ \text{mmHg} = 22664.802632 \ \text{Pa}$$
