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

Kilopascal

One kilopascal equals $10^3$ pascals.

How to convert Millimeters of mercury to Kilopascal

$$\text{Pressure}_{\text{kPa}} = \text{Pressure}_{\text{mmHg}} \cdot 0.1333223684210526315789473684210526$$

Examples

Example 1

Convert $30.0\ \text{mmHg}$ to $\text{kPa}$.

$$\text{Pressure}_{\text{kPa}} = 30.0 \cdot 0.1333223684210526315789473684210526$$

$$\text{Pressure}_{\text{kPa}} = 3.999671$$

$$\therefore \ 30.0\ \text{mmHg} = 3.999671 \ \text{kPa}$$

Example 2

Convert $70.0\ \text{mmHg}$ to $\text{kPa}$.

$$\text{Pressure}_{\text{kPa}} = 70.0 \cdot 0.1333223684210526315789473684210526$$

$$\text{Pressure}_{\text{kPa}} = 9.332566$$

$$\therefore \ 70.0\ \text{mmHg} = 9.332566 \ \text{kPa}$$

Example 3

Convert $110.0\ \text{mmHg}$ to $\text{kPa}$.

$$\text{Pressure}_{\text{kPa}} = 110.0 \cdot 0.1333223684210526315789473684210526$$

$$\text{Pressure}_{\text{kPa}} = 14.665461$$

$$\therefore \ 110.0\ \text{mmHg} = 14.665461 \ \text{kPa}$$

Example 4

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

$$\text{Pressure}_{\text{kPa}} = 145.0 \cdot 0.1333223684210526315789473684210526$$

$$\text{Pressure}_{\text{kPa}} = 19.331743$$

$$\therefore \ 145.0\ \text{mmHg} = 19.331743 \ \text{kPa}$$

Example 5

Convert $180.0\ \text{mmHg}$ to $\text{kPa}$.

$$\text{Pressure}_{\text{kPa}} = 180.0 \cdot 0.1333223684210526315789473684210526$$

$$\text{Pressure}_{\text{kPa}} = 23.998026$$

$$\therefore \ 180.0\ \text{mmHg} = 23.998026 \ \text{kPa}$$
