BMI Calculator
A BMI Calculator is used to estimate body fat based on a person’s height and weight. BMI, or Body Mass Index, is a commonly used screening tool that helps categorize weight status for adults.
While BMI does not directly measure body fat, it provides a simple way to assess whether a person’s weight is within a healthy range.
What Is BMI (Body Mass Index)?
Body Mass Index (BMI) is a numerical value calculated using height and weight. It is widely used in healthcare and fitness settings to classify weight status.
BMI is intended for:
- Adults aged 18 and older
- General health screening
- Population-level assessments
It is not a diagnostic tool but can indicate potential health risks.
What the BMI Calculator Does
The BMI Calculator allows you to:
- Calculate BMI using height and weight
- Instantly see your BMI value
- Identify your BMI category
- Avoid manual calculations
The calculator supports both metric and imperial measurements.
BMI Calculator for Women
The BMI Calculator for Women helps women quickly determine their Body Mass Index based on height and weight. This female BMI calculator provides accurate results to show whether you are underweight, normal weight, overweight, or obese according to standard BMI ranges. Designed specifically as a BMI calculator women can rely on, it makes tracking health and fitness goals simple and convenient.BMI Formula
Metric Formula
BMI = weight (kg) ÷ height² (m²)
Imperial Formula
BMI = (weight (lb) ÷ height² (in²)) × 703
The calculator applies the correct formula automatically based on the units entered.
Example BMI Calculation
Example (Metric):
- Weight: 70 kg
- Height: 1.75 m
Calculation:
BMI = 70 ÷ (1.75 × 1.75) = 22.86
Result:
BMI ≈ 22.9
BMI Categories
BMI values are grouped into standard categories:
| BMI Range | Category |
|---|---|
| Below 18.5 | Underweight |
| 18.5 – 24.9 | Normal weight |
| 25.0 – 29.9 | Overweight |
| 30.0 and above | Obese |
These categories help assess general health risk.
How BMI Is Commonly Used
BMI is often used for:
- Health and wellness screening
- Fitness tracking
- Medical assessments
- Public health research
Healthcare professionals may use BMI alongside other measurements for better accuracy.
Limitations of BMI
BMI does not account for:
- Muscle mass
- Bone density
- Body fat distribution
- Age or gender differences
As a result, athletes or muscular individuals may have a high BMI without excess body fat.
