Body Mass Index Calculator

Body Mass Index (BMI) is a simple measurement that uses your height and weight to determine if you’re in a healthy weight range. It’s widely used by healthcare professionals in Tanzania and globally as a screening tool.

BMI helps identify potential weight-related health risks. While it doesn’t directly measure body fat, it provides a useful indicator for most adults aged 18-65 years.

Understanding your BMI is particularly important in Tanzania where lifestyle diseases like diabetes and hypertension are becoming more common in urban areas.
