Blood pressure is usually measured by wrapping a closed air-filled jacket equipped with a pressure gage around the upper arm of a person at the level of the heart. Using a mercury manometer and a stethoscope, the systolic pressure (the maximum pressure when the heart is pumping) and the diastolic pressure (the minimum pressure when the heart is resting) are measured in $\mathrm{mm} \mathrm{Hg}$. The systolic and diastolic pressures of a healthy person are about $120 \mathrm{~mm} \mathrm{Hg}$ and 80 $\mathrm{mm} \mathrm{Hg}$, respectively, and are indicated as 120/80. Express both of these gage pressures in $\mathrm{kPa}$, psi, and meter water column.
