BMI Calculator
Calculate your Body Mass Index in metric or imperial units and see the healthy weight range for your height.
BMI is a screening figure, not a diagnosis. It cannot tell muscle from fat and does not fit every body or every population. Talk to a healthcare professional before acting on it.
About the bmi calculator
BMI divides your weight by the square of your height to produce a single number that roughly indicates whether your weight is in a healthy range for your height. It is a screening tool, not a diagnosis. It cannot distinguish muscle from fat, and it systematically misreads very muscular people, older adults who have lost muscle mass, and some ethnic groups for whom the standard thresholds do not fit well. Use it as one data point among several, and talk to a doctor about the rest.
