Question

You inflate the front tires on your car to 28.2 psi. Later, you measure your blood pressure, obtaining a reading of 113/90.7, the readings being in mm Hg. In metric countries (which is to say, most of the world), these pressures are customarily reported in kilopascals (kPa). In kilopascals, what are (a) your tire pressure and (b) the upper level and (c) the lower level of your blood pressure?

Explanation / Answer

(a) 1 psi = 6.894757 kPa

So, 28.2 psi = 28.2 * 6.894757 kPa = 194.4321474 kPa

(b) 1 mm Hg = 0.133322387415 kPa

113 mm Hg = 113 * 0.133322387415 kPa = 15.0654297779 kPa

(c) 90.7 mm Hg = 90.7 * 0.133322387415 kPa = 12.0923405385 kPa
