How the BMI Calculator for Amputation Works

This bmi calculator for amputation uses established body segment weight percentages to estimate missing mass:

  • Hand: 0.6% of total body weight
  • Forearm: 1.6%
  • Full Arm: 5.1%
  • Foot: 1.5%
  • Below Knee: 8.3%
  • Above Knee: 16.1%
  • Hip Disarticulation: 19%
Adjusted Weight = Current Weight × (100 / (100 - Total Adjustment %))
BMI = (Adjusted Weight / (Height m)²)
