Key Concepts

Pressure Units

Pressure is a measure of the force exerted by a fluid per unit area. Common units for pressure include inches of mercury (in Hg), millimeters of mercury (mmHg), and pascals (Pa). Understanding how to convert between these units is essential for solving problems related to pressure in different contexts.

Unit Conversion

Unit conversion involves changing a quantity expressed in one unit to another unit without changing its value. For pressure, the conversion between in Hg and mmHg is straightforward, as 1 in Hg is equivalent to 25.4 mmHg. Mastery of conversion factors is crucial for accurately interpreting and comparing measurements.

Barometric Pressure

Barometric pressure refers to the pressure exerted by the weight of the atmosphere at a given location. It varies with altitude, with lower pressures found at higher elevations. In Denver, the average pressure of 24.9 in Hg reflects its elevation of 5280 ft, which is important for understanding how atmospheric conditions affect pressure readings.
