Convert a pressure of 10 psi to inches of mercury. How many inches of mercury is the pressure?

Convert a pressure of 10 psi to inches of mercury. How many inches of mercury is the pressure?

• A. 15 inches of mercury
• B. 20 inches of mercury
• C. 25 inches of mercury
• D. 30 inches of mercury

Answer: (B)

To convert a pressure measurement from psi (pounds per square inch) to inches of mercury (inHg), you can use the conversion factor where 1 psi is equivalent to approximately 2.036 inches of mercury. Applying this conversion to a pressure of 10 psi involves multiplying 10 psi by the conversion factor: 10 psi × 2.036 inHg/psi = 20.36 inHg. When rounding to whole numbers, this value approximates to 20 inches of mercury. Therefore, the correct conversion from 10 psi to inches of mercury is approximately 20 inches, making it the correct answer in the context of the question. The other options reflect incorrect calculations or conversions based on this established conversion factor.
