B.M, or Body Mass, is a measurement that helps assess an individual's body weight in relation to their height. It is commonly used to categorize people into different weight classifications, such as underweight, normal weight, overweight, and obese. This classification can provide insights into potential health risks associated with body weight. The calculation of B.M is typically done using the formula: weight in kilograms divided by height in meters squared. Health professionals often use B.M as a screening tool to identify individuals who may benefit from lifestyle changes or medical interventions related to their weight and overall health.
