How many pounds does one cubic inch of mercury weigh?

• A. 0.036
• B. 0.491
• C. 2.6
• D. 3.7

Answer: (B)

One cubic inch of mercury weighs approximately 0.491 pounds. This value is derived from the density of mercury, which is about 13.6 grams per cubic centimeter. When converting this density into pounds per cubic inch, it becomes clear that a cubic inch of mercury will indeed weigh around 0.491 pounds. This weight is significant in applications involving pressure measurement, where mercury is commonly used due to its dense properties. Understanding this weight is essential for calculations involving pressure gauges and related devices in plumbing and pipefitting scenarios.
