## Overview

The Body Adiposity Index (BAI) Calculator provides a simple way to estimate your body fat percentage by using your hip circumference and height measurements. Unlike traditional BMI, the BAI offers an alternative metric for assessing body composition based on physical dimensions.

## Inputs

- **Hip Circumference (cm)** (number): Enter hip circumference at widest point
- **Height (cm)** (number): Enter your height
- **Gender** (select)
- **Age (optional)** (number): Enter your age

## When to use

- When you want to estimate body fat percentage without specialized equipment.
- When you are tracking changes in body composition over time.
- When you need a supplementary metric to compare alongside your BMI.

## How it works

- Enter your hip circumference measured at the widest point in centimeters.
- Input your current height in centimeters.
- Select your gender and optionally provide your age for a more tailored profile.
- Click calculate to receive your estimated Body Adiposity Index score.

## Use cases

- Fitness enthusiasts monitoring body composition changes during a training program.
- Individuals seeking a quick, non-invasive way to estimate body fat at home.
- Health-conscious users comparing different body metrics to better understand their physical status.

## Frequently asked questions

### What is the Body Adiposity Index (BAI)?

BAI is a mathematical formula that estimates body fat percentage based on hip circumference and height.

### How is BAI different from BMI?

BMI uses weight and height, while BAI uses hip circumference and height, which some researchers believe provides a better estimate of body fat.

### Is the BAI calculation accurate?

BAI is an estimation tool. It is not a substitute for professional medical diagnostic tests like DEXA scans.

### Do I need to provide my age?

No, age is optional. Providing it helps refine the context of your health profile.

### What units of measurement are required?

The calculator requires measurements in centimeters (cm).

- [Alveolar Gas Equation (PAO₂ Calculator)](https://elysiatools.com/en/tools/alveolar-gas-equation): Calculate PAO₂ = FiO₂ × (P_atm − 47) − PaCO₂ / RQ. Defaults: P_atm 760 mmHg (sea level), RQ 0.8. Gives a directional hint vs expected ~100 mmHg. For full A-a gradient interpretation use a-a-gradient-calculator. Derived from StatPearls, LITFL, Cornell PICU, and West. Not medical advice.
- [Alveolar Ventilation Calculator (VA)](https://elysiatools.com/en/tools/alveolar-ventilation-calculator): Calculate VA = (VT − VD) × RR in L/min. VD may be supplied or estimated as ~2 mL/kg body weight. Normal resting ~4–6 L/min; low → hypercapnia, high → hypocapnia. Derived from West, LITFL, StatPearls, and Radford 1955. Not medical advice.
- [Cardiac Index Calculator (CI)](https://elysiatools.com/en/tools/cardiac-index-calculator): Compute CI = CO / BSA with BSA from the Mosteller formula √(height × weight / 3600). Normal 2.5–4.0 L/min/m². Derived from Mosteller NEJM 1987, Du Bois 1916, StatPearls, LITFL. Not medical advice.
- [Dose by Body Surface Area Calculator (BSA = √(H·W/3600))](https://elysiatools.com/en/tools/dose-by-body-surface-area): Calculate an individualized drug dose from body surface area using the Mosteller formula: BSA (m²) = √(Height(cm) · Weight(kg) / 3600), then Dose = Drug_dose_per_m² × BSA. BSA is the recommended normalization for many cytotoxic and pediatric regimens because drug clearance scales more linearly with BSA than with body weight across patients of different sizes. Also reports the standard adult dose at the reference adult BSA of 1.73 m² for comparison. Valid only for linear drug clearance — BSA dosing does not apply to saturable (Michaelis-Menten) pathways. Not medical advice.
- [Left Ventricular Ejection Fraction Estimator (LVEF)](https://elysiatools.com/en/tools/ejection-fraction-estimator): Compute LVEF = (EDV − ESV) / EDV. Normal 50–70%; <40% HFrEF; >70% hyperdynamic. Derived from Lang JASE 2015, Ponikowski ESC 2016, StatPearls, LITFL, Braunwald. Not medical advice.
- [LDL-C Calculator (Friedewald)](https://elysiatools.com/en/tools/ldl-calculator-friedewald): Calculate LDL-C (low-density lipoprotein cholesterol) indirectly with the Friedewald formula. In mg/dL: LDL-C = Total Cholesterol − HDL-C − (Triglycerides / 5); in mmol/L: LDL-C = TC − HDL-C − (TG / 2.2). Unreliable when triglycerides ≥ 400 mg/dL (4.5 mmol/L), in the non-fasting state, in type III dysbetalipoproteinemia, and at very low LDL-C (< 70 mg/dL). Treatment thresholds (ACC/AHA 2018): < 70 mg/dL (1.8 mmol/L) high-risk secondary prevention; < 100 mg/dL (2.6 mmol/L) moderate-risk / diabetes primary prevention; ≥ 190 mg/dL (4.9 mmol/L) suggests familial hypercholesterolemia. Unit system selectable: mg/dL or mmol/L. Derived from Friedewald 1972, Martin 2013, Sampson 2020, and ACC/AHA 2018. Not medical advice.
