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 provides a standardized weight calculation for females.

2. How Does the Calculator Work?

The calculator uses the Devine formula for females:

Where:

• \( height \) — Height in centimeters (cm)
• 45.5 — Base weight in kilograms
• 0.91 — Weight increment per cm above 152.4 cm
• 152.4 — Reference height in cm (5 feet)

Explanation: The formula calculates ideal body weight by adding 45.5 kg to 0.91 kg for each centimeter over 152.4 cm (5 feet).

3. Importance of Ideal Body Weight Calculation

Details: Ideal body weight is used in clinical settings for medication dosing, nutritional assessment, and determining appropriate weight goals for patients.

4. Using the Calculator

Tips: Enter height in centimeters. The value must be valid (height > 0). The calculator will provide the ideal body weight in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: What is the male version of this formula?
A: For males, the Devine formula is: IBW (kg) = 50 + 0.91 × (height (cm) - 152.4)

Q2: How accurate is the Devine formula?
A: While widely used, it may overestimate IBW in shorter individuals and underestimate in taller individuals. It's best used as a general guideline.

Q3: Are there other IBW formulas available?
A: Yes, other formulas include the Robinson formula, Miller formula, and Hamwi method, each with slightly different calculations.

Q4: When should IBW be used clinically?
A: IBW is commonly used for drug dosing calculations, nutritional assessment, and determining appropriate weight ranges for patients.

Q5: Does this formula account for body frame size?
A: No, the Devine formula does not account for body frame size. Adjustments may be needed for individuals with small or large frames.
