1. What is the Weight Formula?

The weight formula calculates body weight based on Body Mass Index (BMI) and height. It provides an estimate of appropriate weight for a given height according to BMI standards.

2. How Does the Calculator Work?

The calculator uses the weight formula:

\[ \text{weight (kg)} = \text{BMI (kg/m²)} \times [\text{height (m)}]^2 \]

Where:

\( BMI \) — Body Mass Index (kg/m²)
\( height \) — Height in meters

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

3. Importance of Weight Calculation

Details: This calculation helps determine appropriate weight ranges for health goals, nutritional planning, and fitness programs based on BMI categories.

4. Using the Calculator

Tips: Enter BMI in kg/m² (typically between 18.5-24.9 for healthy range) and 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: Generally 18.5-24.9 kg/m² is considered healthy, though individual factors may vary.

Q2: How do I convert height from cm to m?
A: Divide centimeters by 100 (e.g., 175 cm = 1.75 m).

Q3: Is this calculation accurate for everyone?
A: It provides an estimate but doesn't account for muscle mass, bone density, or body composition differences.

Q4: Can I use this for children?
A: BMI calculations for children require age- and sex-specific percentiles rather than fixed ranges.

Q5: What if I want to calculate in pounds?
A: Multiply the kg result by 2.205 to convert to pounds.
