Calculating body mass index (BMI) online is a convenient and accessible method to assess body weight status. It involves inputting personal data, such as height and weight, into an online calculator, which then computes the BMI value.
BMI is a valuable tool for understanding health risks associated with weight. It provides individuals with an indicator of whether their weight is within a healthy range, underweight, overweight, or obese. Historically, BMI was developed in the 19th century as a way to classify individuals based on body size and weight.
