1. What is the Reverse BMI Calculator?

The Reverse BMI Calculator calculates weight from height and BMI using the standard BMI formula rearranged to solve for weight. This is useful for determining target weights based on desired BMI values.

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: This formula rearranges the standard BMI calculation (BMI = Weight / Height²) to solve for weight instead of BMI.

3. Importance of Weight Calculation

Details: Calculating target weight based on desired BMI helps in setting realistic weight goals, planning weight management programs, and understanding healthy weight ranges for specific heights.

4. Using the Calculator

Tips: Enter BMI value (unitless) and height in meters. Both values must be positive numbers. The calculator will compute the corresponding weight in kilograms.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy BMI range?
A: For most adults, a BMI between 18.5 and 24.9 is considered healthy. Below 18.5 is underweight, 25-29.9 is overweight, and 30+ is obese.

Q2: Why use meters for height?
A: The BMI formula requires height in meters squared. If you have height in other units, convert to meters first (1 foot = 0.3048 meters, 1 inch = 0.0254 meters).

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

Q4: Can I use this for children?
A: BMI calculations for children and teens use age and sex-specific percentiles rather than the standard adult categories.

Q5: What are the limitations of BMI?
A: BMI doesn't distinguish between muscle and fat, so athletes with high muscle mass may have high BMI without being overweight.
