1. What is the Devine Formula?

The Devine formula is a method for estimating ideal body weight (IBW) based on height. It provides a standardized weight range that is considered healthy for a given height, primarily used for medical purposes.

2. How Does the Calculator Work?

The calculator uses the Devine formula:

Where:

• \( Height \) — Height in inches
• 50 — Base weight in kg for 5 feet (60 inches)
• 2.3 — Additional kg per inch over 5 feet

Explanation: The formula calculates ideal body weight by adding 2.3 kg for each inch over 5 feet (60 inches) to a base weight of 50 kg.

3. Importance of Ideal Body Weight Calculation

Details: Ideal body weight calculation is important for determining appropriate medication dosages, nutritional assessments, and setting healthy weight goals in clinical practice.

4. Using the Calculator

Tips: Enter height in inches. The value must be valid (height > 0).

5. Frequently Asked Questions (FAQ)

Q1: Is this formula the same for men and women?
A: The Devine formula is primarily used for men. For women, a common adjustment is to use 45.5 kg as the base weight instead of 50 kg.

Q2: What are the limitations of the Devine formula?
A: The formula doesn't account for body composition, frame size, or muscle mass, and may not be accurate for very tall or very short individuals.

Q3: How accurate is this calculation?
A: It provides a rough estimate of ideal body weight but should be used as a guideline rather than an absolute measure.

Q4: Can this be used for children?
A: No, the Devine formula is designed for adults. Different formulas and growth charts are used for pediatric populations.

Q5: How is this different from BMI?
A: While BMI considers both weight and height, IBW provides a target weight range for a given height without considering current weight.
