Formula Behind the Weight by Height Calculator
This calculator is based on a simplified version of the Broca Index formula, which estimates ideal body weight using height and gender adjustments.
Base Weight Formula
Base Weight=(Height−100)×Factor
Where:
- Height is in cm
- Factor depends on gender:
- Male = 0.9
- Female = 0.85
Adjusted Weight with Body Frame
Adjusted Weight=Base Weight×Frame Factor
Where:
- Small Frame = 0.95
- Medium Frame = 1.00
- Large Frame = 1.05
Final Weight Range Formula
Weight Range=Adjusted Weight±10%
This gives a realistic healthy range instead of a single number.
Example Calculation
Let’s understand this with a real-life example.
Given:
- Height = 170 cm
- Gender = Male
- Body Frame = Medium (1.00)
Step 1: Calculate Base Weight
Base Weight = (170 – 100) × 0.9
Base Weight = 70 × 0.9 = 63 kg
Step 2: Apply Frame Factor
Adjusted Weight = 63 × 1.00 = 63 kg
Step 3: Calculate Range
- Minimum Weight = 63 × 0.9 = 56.7 kg
- Maximum Weight = 63 × 1.1 = 69.3 kg
Final Result:
👉 Ideal Weight Range = 56.7 kg – 69.3 kg
