What is the metric equivalent of calculating head pressure when height is measured in meters?

To determine the metric equivalent of calculating head pressure when using height measured in meters, it is essential to understand the relationship between height and pressure in fluid dynamics. The pressure head can be calculated using the formula:

Pressure (in pascals) = 9.81 m/s² × height (in meters)

This formula derives from the weight of a column of fluid and the acceleration due to gravity (approximately 9.81 m/s²). Therefore, when height is measured in meters, the conversion factor to find the equivalent pressure head in pascals results in approximately 9.81.

Using this relationship, if you have a height of one meter of water, it equates to a pressure head of about 9.81 kPa (kilopascals). Hence, when calculating head pressure in a metric system where the height is measured in meters, the correct conversion factor to use is indeed around 9.81. This is why the answer provided corresponds accurately to the understanding of pressure head in fluid systems.
