How to Use the Adjusted Body Weight Calculator
- Select your gender (Male or Female) from the dropdown.
- Enter your actual weight in kilograms (e.g., 100).
- Enter your height in centimeters (e.g., 175).
- Click "Calculate Adjusted Body Weight".
What it does:
- First calculates your Ideal Body Weight (IBW) using the Devine formula:
- Male: 50 kg + 0.91 × (height in cm – 152.4)
- Female: 45.5 kg + 0.91 × (height in cm – 152.4)
- Then computes the Adjusted Body Weight (ABW) as:
ABW = IBW + 0.4 × (actual weight – IBW)
Important: All values must be in metric units (kg and cm). The result shows your adjusted weight in kilograms, with a full formula breakdown.

Frequently Asked Questions
Adjusted body weight is a formula used to estimate a more accurate body weight for obese individuals when calculating nutritional needs. It accounts for excess weight by adding a fraction of the difference between actual weight and ideal body weight.
For males: IBW = 50 kg + 0.91 kg per cm over 152.4 cm. For females: IBW = 45.5 kg + 0.91 kg per cm over 152.4 cm.
ABW is often used in clinical settings for patients with obesity (BMI ≥ 30) to estimate energy and protein requirements more accurately than using actual or ideal body weight alone.
