1. What is the Reverse BMI Calculator?

The Reverse BMI Calculator determines a person's weight based on their Body Mass Index (BMI) and height. This is useful when you know your BMI and height but want to find your ideal or target weight.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ Weight = BMI \times Height^2 \]

Where:

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

3. Importance of Weight Calculation

Details: Knowing your target weight based on a healthy BMI range can help with weight management goals, fitness planning, and overall health monitoring.

4. Using the Calculator

Tips: Enter your BMI value (typically between 18.5-24.9 for healthy range) and your height in meters. All values must be valid (BMI > 0, height > 0).

5. Frequently Asked Questions (FAQ)

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

Q2: How accurate is this calculation?
A: This calculation provides a theoretical weight based on the BMI formula. Individual factors like muscle mass, bone density, and body composition may affect actual healthy weight ranges.

Q3: Can I use this for children?
A: No, BMI calculations for children and teens use age and sex-specific percentiles rather than the standard adult formula.

Q4: What if I know my height in feet/inches?
A: Convert your height to meters first (1 foot = 0.3048 meters, 1 inch = 0.0254 meters) before using this calculator.

Q5: Should I use this target weight for weight loss goals?
A: While this provides a general guideline, consult with a healthcare provider for personalized weight management advice based on your specific health status.
