Health 101™ IBW-hamwi computations are based on inches and pounds, according to the following:
M = 106 lb for the first 5 ft + 6 lb for each additional inch.
M = 48 kg for the first 152.4 cm + 1.1 kg for each additional cm.
F = 100 lb for the first 5 ft + 5 lb for each additional inch.
F = 45 kg for the first 152.4 cm + 0.9 kg for each additional cm.
