TABLE 1.

Body weight equation at key BMI values

BMI, kg/m2	US version	Metric version
	Wt (lb) = 5 × BMI + (BMI ÷ 5) × (Ht − 60 in)	Wt (kg) = 2.2 × BMI + 3.5 × BMI × (Ht − 1.5 m)
20	Wt (lb) = 100 + 4 × (Ht − 60 in)	Wt (kg) = 44 + 70 × (Ht − 1.5 m)
25	Wt (lb) = 125 + 5 × (Ht − 60 in)	Wt (kg) = 55 + 88 × (Ht − 1.5 m)
30	Wt (lb) = 150 + 6 × (Ht − 60 in)	Wt (kg) = 66 + 105 × (Ht − 1.5 m)
35	Wt (lb) = 175 + 7 × (Ht − 60 in)	Wt (kg) = 77 + 123 × (Ht − 1.5 m)
40	Wt (lb) = 200 + 8 × (Ht − 60 in)	Wt (kg) = 88 + 140 × (Ht − 1.5 m)
45	Wt (lb) = 225 + 9 × (Ht − 60 in)	Wt (kg) = 99 + 158 × (Ht − 1.5 m)
50	Wt (lb) = 250 + 10 × (Ht − 60 in)	Wt (kg) = 110 + 175 × (Ht − 1.5 m)
