BMI Calculator – Check Your Body Mass Index Easily

Maintaining a healthy weight is important for overall health and wellness. A BMI Calculator helps you quickly determine whether your weight falls within a healthy range based on your height and weight. BMI, or Body Mass Index, is one of the most commonly used methods for evaluating body weight categories in adults.

Whether you are tracking fitness goals, planning weight loss, or monitoring your health, a BMI Calculator provides a fast and simple way to understand your body composition.

What Is a BMI Calculator?

A BMI Calculator is an online health tool used to calculate your Body Mass Index (BMI) using your height and weight.

The calculator helps determine whether you are:

• Underweight
• Normal weight
• Overweight
• Obese

BMI is widely used by healthcare professionals as a general indicator of healthy body weight.

BMI Formula

The standard BMI formula is:

BMI=Weight (kg)Height (m)2BMI=\frac{Weight\ (kg)}{Height\ (m)^2}BMI=Height (m)2Weight (kg)​

For imperial measurements:

BMI=Weight (lb)×703Height (in)2BMI=\frac{Weight\ (lb)\times703}{Height\ (in)^2}BMI=Height (in)2Weight (lb)×703​

Where:

• Weight = Body weight
• Height = Height measurement
• BMI = Body Mass Index value

Example BMI Calculation

Suppose:

• Weight = 70 kg
• Height = 1.75 m

The calculation becomes:

701.752=22.86\frac{70}{1.75^2}=22.861.75270​=22.86

Your BMI would be approximately 22.9, which falls within the healthy weight range.
