1. What is the Devine Formula?

The Devine formula is a method for estimating ideal body weight (IBW) based on height. It was originally developed for medication dosing and has become one of the most commonly used equations for estimating ideal weight in clinical practice.

2. How Does the Calculator Work?

The calculator uses the Devine formula:

Where:

• \( IBW \) — Ideal Body Weight in kilograms
• \( height \) — Height in inches

Explanation: The formula assumes an ideal weight of 50 kg for a person who is 5 feet (60 inches) tall, with an additional 2.3 kg for each additional inch of height.

3. Importance of Ideal Weight Calculation

Details: Ideal body weight calculations are used in various medical contexts, including medication dosing, nutritional assessment, and determining appropriate weight goals for patients.

4. Using the Calculator

Tips: Enter height in inches. The value must be valid (height > 0). For height in feet and inches, convert to total inches first (1 foot = 12 inches).

5. Frequently Asked Questions (FAQ)

Q1: Is the Devine formula accurate for everyone?
A: The formula provides a general estimate but may not be accurate for individuals with very high muscle mass, athletes, or those with certain body compositions.

Q2: Are there different formulas for men and women?
A: Some variations of the formula use different base weights for men and women, but the standard Devine formula is the same for both genders.

Q3: How should ideal weight be used in clinical practice?
A: Ideal weight is often used as a reference point for medication dosing, nutritional assessment, and setting weight management goals.

Q4: What are the limitations of this formula?
A: The formula doesn't account for frame size, muscle mass, or body fat percentage, which can significantly affect ideal weight.

Q5: Can this formula be used for children?
A: No, the Devine formula is designed for adults. Different formulas and growth charts are used for pediatric populations.
