## Overview

The BMI Calculator for Children provides an accurate way to assess body mass index for individuals aged 2 to 20, utilizing age and gender-specific growth charts to determine weight status percentiles.

## Inputs

- **Age** (number): Enter age (2-20 years)
- **Gender** (select)
- **Measurement System** (select)
- **Weight** (number): Enter weight
- **Weight Unit** (select)
- **Height** (number): Enter height
- **Height Unit** (select)

## When to use

- Monitoring a child's growth trends during routine health check-ups.
- Assessing whether a child's weight is within a healthy range for their specific age and gender.
- Providing pediatricians or parents with data-driven insights into a child's physical development.

## How it works

- Enter the child's age, gender, and current height and weight measurements.
- Select your preferred measurement system, either metric or imperial units.
- The tool calculates the BMI and compares it against standard growth percentiles to provide a health context.

## Use cases

- Tracking annual growth progress for school-aged children.
- Assisting parents in understanding their child's weight status based on clinical standards.
- Supporting health educators in demonstrating the importance of growth monitoring.

## Frequently asked questions

### Why is BMI for children different from adults?

Children are still growing, so their BMI must be interpreted relative to other children of the same age and gender using percentile charts.

### What age range does this calculator support?

This tool is designed for children and adolescents between the ages of 2 and 20 years old.

### Can I use imperial units like pounds and inches?

Yes, the calculator supports both metric (kg, cm) and imperial (lb, ft/in) measurement systems.

### What does the percentile result mean?

The percentile indicates how a child's BMI compares to the reference population; for example, the 50th percentile is the median BMI for that age and gender.

### Is this tool a substitute for medical advice?

No, this tool is for informational purposes only and should not replace professional medical diagnosis or consultation.

- [Bioavailability Calculator (F = AUC_po · Dose_iv / AUC_iv · Dose_po)](https://elysiatools.com/en/tools/bioavailability-calculator): Calculate the absolute bioavailability F of an extravascular (typically oral) dose: F = (AUC_po · Dose_iv) / (AUC_iv · Dose_po), where AUC_po and AUC_iv are the areas under the concentration-time curve after oral and IV dosing, and the doses correct for any difference in amount administered. F is dimensionless and lies in \[0, 1\]; IV bioavailability is by definition 1, while oral F < 1 reflects incomplete absorption and/or first-pass metabolism. AUC can be in any consistent unit (e.g. mg·h/L) since it cancels out of the ratio. Valid only for linear pharmacokinetics, the same drug molecule, and doses within the linear range.
