1. What is the Reverse BMI Calculator?

The Reverse BMI Calculator calculates weight from BMI and height using the formula: Weight = BMI × Height². This is useful for determining the target weight corresponding to a specific BMI value.

2. How Does the Calculator Work?

The calculator uses the reverse BMI formula:

Where:

• \( BMI \) — Body Mass Index (unitless)
• \( Height \) — Height in meters (m)
• \( Weight \) — Weight in kilograms (kg)

Explanation: The formula rearranges the standard BMI calculation to solve for weight instead of BMI.

3. Importance of Weight Calculation

Details: Calculating weight from BMI helps individuals set realistic weight goals based on their desired BMI category and height.

4. Using the Calculator

Tips: Enter BMI value (unitless) and height in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: A BMI between 18.5 and 24.9 is generally considered healthy for most adults.

Q2: Can this calculator be used for children?
A: No, this calculator uses the standard adult BMI formula. Pediatric BMI calculations require age and sex-specific percentiles.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise, but actual healthy weight ranges may vary based on individual factors like body composition.

Q4: What if I want to use imperial units?
A: Convert height to meters first (1 inch = 0.0254 meters) for accurate results.

Q5: Does this account for muscle mass?
A: No, BMI doesn't distinguish between muscle and fat mass. Athletes with high muscle mass may have higher BMI values.
