A BMI calculator is a simple web application that allows users to input their height and weight to calculate their body mass index (BMI). It provides an easy way for people to assess if they are in a healthy weight range for their height.
A BMI calculator is a tool available on many health and fitness websites that allows an individual to input their height and weight details to calculate their body mass index (BMI) value. BMI is a measurement that uses a person's height and weight to indicate if they are at a healthy weight, underweight, overweight or obese according to standard ranges.
Online BMI calculators provide a quick and convenient way for people to determine their BMI. They typically require a user to input just two pieces of information - their height in either inches/feet or centimeters/meters, and their current weight in either pounds or kilograms. Once submitted, the calculator will use a standard BMI formula to instantly generate the user's BMI number along with a classification of whether they fall into a healthy, underweight, overweight or obese BMI category.
The advantage of using an online BMI calculator is receiving an immediate assessment of weight status without needing to consult a doctor or buy equipment. However, BMI is just a screening tool and does have limitations. BMI calculations don't account for age, gender, bone structure or muscle mass when determining if weight is appropriate. So further evaluations by a physician may be required to get an exact picture of an individual's health.
