Pressure Conversion Problem
The pressure reading from a barometer is 742 mm Hg. Express this reading in kilopascals, kPa.
This conversion may be performed using two conversion factors:
760 mm Hg = 1.013 x 105 Pa
1 kPa = 103Pa
742 mm Hg x 1.013 x 105 Pa / 760 mm Hg x 1 kPa / 103 Pa = 98.9 kPa
Always ask yourself whether your final answer seems reasonable. Atmospheric pressure is usually close to 100 kPa, so an answer of 98.9 kPa is reasonable.
