Answer :

To convert the systolic pressure from millimeters of mercury (mm Hg) to pounds per square inch (psi), follow these steps:

1. Identify the given values and the conversion factor:
- The systolic pressure is [tex]\( 77.1 \)[/tex] mm Hg.
- The conversion factor to convert mm Hg to psi is: [tex]\( 1 \text{ mm Hg} = 0.0193368 \text{ psi} \)[/tex].

2. Perform the conversion:
- Multiply the systolic pressure in mm Hg by the conversion factor to obtain the pressure in psi:
[tex]\[ 77.1 \text{ mm Hg} \times 0.0193368 \text{ psi/mm Hg} \][/tex]

3. Calculate the result:
- When you multiply these values, you get:
[tex]\[ 77.1 \times 0.0193368 = 1.49156688 \text{ psi} \][/tex]

4. Round the result:
- Round the result to two decimal places for simplicity and readability:
[tex]\[ 1.49156688 \approx 1.49 \][/tex]

Therefore, the systolic pressure converted to psi, rounded to two decimal places, is [tex]\( 1.49 \)[/tex] psi.
