Kilopascal

One kilopascal equals $10^3$ pascals.

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 Kilopascal to Millimeters of mercury

$$\text{Pressure}_{\text{mmHg}} = \text{Pressure}_{\text{kPa}} \cdot 7.500616827041697508018751542067604$$

Examples

Example 1

Convert $25.0\ \text{kPa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 25.0 \cdot 7.500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 187.515421$$

$$\therefore \ 25.0\ \text{kPa} = 187.515421 \ \text{mmHg}$$

Example 2

Convert $65.0\ \text{kPa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 65.0 \cdot 7.500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 487.540094$$

$$\therefore \ 65.0\ \text{kPa} = 487.540094 \ \text{mmHg}$$

Example 3

Convert $100.0\ \text{kPa}$ to $\text{mmHg}$.

$$\text{Pressure}_{\text{mmHg}} = 100.0 \cdot 7.500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 750.061683$$

$$\therefore \ 100.0\ \text{kPa} = 750.061683 \ \text{mmHg}$$

Example 4

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

$$\text{Pressure}_{\text{mmHg}} = 135.0 \cdot 7.500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 1012.583272$$

$$\therefore \ 135.0\ \text{kPa} = 1012.583272 \ \text{mmHg}$$

Example 5

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

$$\text{Pressure}_{\text{mmHg}} = 180.0 \cdot 7.500616827041697508018751542067604$$

$$\text{Pressure}_{\text{mmHg}} = 1350.111029$$

$$\therefore \ 180.0\ \text{kPa} = 1350.111029 \ \text{mmHg}$$
