What is the pressure at 5280 ft elevation in Denver, Colorado, converted to various units?

The atmospheric pressure in Denver, Colorado, at an elevation of 5280 feet is approximately 25.3 inches of mercury (inHg). Let’s convert this pressure to different units:

1. a) Convert this pressure to atmospheres:
   To convert inches of mercury to atmospheres, we use the conversion factor: 1 inHg ≈ 0.03342 atm.
   So, the conversion is:
   25.3 inHg * 0.03342 atm/inHg ≈ 0.846 atm
2. b) Convert this pressure to millimeters of mercury:
   We know that 1 inHg is equal to 25.4 mmHg.
   Therefore, the conversion is:
   25.3 inHg * 25.4 mmHg/inHg ≈ 643.42 mmHg
3. c) Convert this pressure to pounds per square inch:
   Using the conversion factor of 1 inHg = 0.4912 psi, we can calculate:
   25.3 inHg * 0.4912 psi/inHg ≈ 12.43 psi
4. d) Convert this pressure to pascals:
   The conversion from inches of mercury to pascals is given by 1 inHg = 3386.39 Pa.
   Thus, the conversion is:
   25.3 inHg * 3386.39 Pa/inHg ≈ 85,703.76 Pa

In summary, the pressure of 25.3 inches of mercury at an elevation of 5280 feet in Denver can be expressed as approximately:

• 0.846 atmospheres
• 643.42 millimeters of mercury
• 12.43 pounds per square inch
• 85,703.76 pascals
