1. What is the Reverse BMI Weight Calculator?

The Reverse BMI Weight Calculator calculates weight from BMI and height using the formula: Weight = BMI × Height². This is useful for determining target weight based on a desired 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 height and desired BMI range for health and fitness purposes.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

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

Q2: Why calculate weight from BMI?
A: This calculation helps determine target weight for achieving a specific BMI, useful for weight management and health goals.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise based on the BMI formula, but individual body composition may vary.

Q4: Can I use different units?
A: The formula requires height in meters. Convert from other units first (1 inch = 0.0254 meters, 1 foot = 0.3048 meters).

Q5: Does this work for children?
A: BMI calculations for children use percentiles rather than fixed ranges. This calculator is designed for adult use.
