You inflate the front tires on your car to 31.4 psi. Later, you measure your blood pressure, obtaining a reading of 120/94.2, 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?
