How high does one inch of mercury lift water in feet?

One inch of mercury is a standard unit of pressure measurement. When it comes to lifting water, the relationship is based on the density differences between mercury and water. The density of mercury is approximately 13.6 times greater than that of water.

To convert inches of mercury to feet of water, a commonly used conversion factor is that 1 inch of mercury can lift water approximately 0.78 feet. However, since the question specifically asks for the equivalent height of water lifted by 1 inch of mercury, using the appropriate conversion gives the correct answer as approximately 1.13 feet. This value arises from calculating how much lower the density of water affects the height to which it would rise compared to mercury under the same pressure.

Thus, one inch of mercury, when converted to water, corresponds to about 1.13 feet of water, making this the accurate response to the question.
