What is BMI?
BMI, which stands for Body Mass Index, is a numerical value that is calculated using a person's weight and height. It is commonly used as a quick and simple way to estimate whether a person has a healthy body weight in relation to their height. BMI is often used as a screening tool to categorize individuals into different weight categories, such as underweight, normal weight, overweight, and obese.

The formula to calculate BMI is:BMI Calculator
Underweight: 0 - 18.5
Normal: 18.5 - 25
Overweight: 25 - 30
Obese: 30 - 35
BMI = weight (kg) / (height (m))^2
The resulting BMI value is then compared to standard ranges to determine the individual's weight category:
Underweight: BMI below 18.5
Normal weight: BMI 18.5 - 24.9
Overweight: BMI 25 - 29.9
Obese: BMI 30 and above
BMI (Body Mass Index) can also be calculated for children to assess their weight status in relation to their height. However, the interpretation of BMI for children is different from adults, as it takes into account the child's age and gender due to variations in growth patterns.
The process of calculating BMI for children is similar to that for adults, but it involves additional steps:
1. Calculate BMI: The formula for calculating BMI for children is the same as for adults:
BMI = weight (kg) / (height (m))^2
2. Determine BMI Percentile: Once the BMI is calculated, it is then plotted on a BMI-for-age growth chart. This chart takes into consideration the child's age and gender. The BMI percentile indicates how a child's BMI compares to other children of the same age and gender. For example, a child with a BMI at the 75th percentile has a higher BMI than 75% of children in the same age and gender group.
3. Interpretation: The BMI percentile is used to categorize a child's weight status:
- Underweight: Less than the 5th percentile
- Healthy weight: 5th percentile to less than the 85th percentile
- Overweight: 85th percentile to less than the 95th percentile
- Obese: Equal to or greater than the 95th percentile
It's important to note that BMI-for-age is a screening tool, and a high or low BMI percentile doesn't necessarily indicate a health problem. Other factors such as growth rate, development, and overall health should be considered when interpreting BMI for children. If you have concerns about your child's weight or growth, it's recommended to consult a pediatrician or healthcare professional for a comprehensive assessment.
