Calculate your Body Mass Index with metric or imperial units.
Body Mass Index (BMI) is a simple measurement used to categorize people into weight groups based on their height and weight. It is a widely used indicator for assessing whether an individual is at a healthy weight for their stature.
While BMI is a helpful screening tool, it is important to note that it does not directly measure body fat or distinguish between muscle and fat mass. Therefore, it should be used as one of many indicators of overall health.
The following categories are based on standard WHO (World Health Organization) guidelines:
BMI may not be highly accurate for very muscular individuals. Because muscle is denser than fat, athletes often have a higher BMI despite having low body fat percentages.
The standard BMI formula does not directly account for age or gender, though these factors are important for a full health assessment. For children and teens, BMI is interpreted differently using age-and-gender-specific percentiles.
