Assumption - weight is measured at sea level where g is constant at 9.81 m/s2
Mass of backpack = 20 kg
Weight = mass x acceleration of gravity
In SI units, g = 9.81 m/s2
W = 20 kg x 9.81 m/s2
= (196.2 kg-m/s2) x (1N / kg-m/s2)
= 196.2 N
In CGS
Mass = 20 kg x 1000g/kg = 20000 g
g = 9.81 m/s2 x 100cm/m = 981 cm/s2
W = 20000 g x 981 cm/s2
= (19620000 g-cm/s2) x (1dyne/ g-cm/s2)
= 19620000 dyne
In US customary units
Mass = 20 kg x 2.205lbm/kg = 44.1 lbm
g = 9.81 m/s2 x 3.2808ft/m = 32.185 ft/s2
W = 44.1 lbm x 32.185 ft/s2
= 1419.12 lbm-ft/s2 x (1 lbf / 32.174 lbm-ft/s2)
= 44.1 lbf
