Pressure P = k H
H = height of mercury column k = proportionality constant
P = M L^-1 T^-2 = k L
so k = M L^-2 T^-2
k = has units of N/m³
at atmospheric pressure , 1 * 10^5 N/m² H = 76 cm = 0.76 meter
so k = 1.31 * 10^5 N/m^3
pressure P = 1.31 * 10^5 H where H is the height of mercury column
H = height of mercury column k = proportionality constant
P = M L^-1 T^-2 = k L
so k = M L^-2 T^-2
