Solution
Solution Steps
Step 1: Understand the Conversion Factor
To convert the atmospheric pressure from millimeters of mercury (mm Hg) to centimeters of mercury (cm Hg), we need to know the conversion factor between these two units.
1 cm = 10 mm
Step 2: Apply the Conversion Factor
Given the barometer reading in millimeters of mercury (530.7 mm Hg), we convert it to centimeters of mercury by dividing by 10.
\[
\text{Pressure in cm Hg} = \frac{\text{Pressure in mm Hg}}{10} = \frac{530.7 \, \text{mm Hg}}{10}
\]
Step 3: Calculate the Result
Perform the division to find the pressure in centimeters of mercury.
\[
\text{Pressure in cm Hg} = 53.07 \, \text{cm Hg}
\]
