According to the formula of Lorentz (accounting for age)
57.8 kilograms or 127.3 pounds.Formula:

- Man (18 more than years old): IBW = -130.736 + (4.064 * h)
- Woman (18 more than 18 years old): IBW = -111.621 + (3.636 * h)
- Boy (18 years old or less): IBW = -59.6035 + (5.2878 * h) - (0.123939 * h2) + (0.00128936 * h3)
- Girl (18 years old or less): IBW = -77.55796 + (6.93728 * h) - (0.171703 * h2) + (0.001726 * h3)
