1. What is BMI?

BMI (Body Mass Index) is a measure that uses your height and weight to work out if your weight is healthy. The NHS children's BMI calculator for women provides a specialized calculation adapted from pediatric growth charts.

2. How Does the Calculator Work?

The calculator uses the standard BMI formula:

Where:

• \( weight \) — Body weight in kilograms
• \( height \) — Height in meters

Explanation: This calculation divides your weight in kilograms by your height in meters squared to determine your BMI category.

3. Importance of BMI Calculation

Details: BMI helps identify potential weight problems in adults (though it's not diagnostic). The NHS children's version provides age-adjusted percentiles for women.

4. Using the Calculator

Tips: Enter weight in kilograms and height in meters. For accuracy, measure height without shoes and weight in light clothing.
