A body mass calculator API is a tool that allows users to calculate their body mass index (BMI).

API description

About the API:

Determine your overall health and fitness based on your weight and height. This API accepts inputs of weight in kilograms or pounds, and height in centimeters, returns a calculated BMI value.

What your API receives and what your API provides (input/output)?

All you have to do is insert your height and weight.


What are the most common uses cases of this API?

    1. Determining if an individual is at a healthy weight for their height: Body mass index (BMI) is a measure that uses your weight and height to determine if you are at a healthy weight. A BMI calculator can help you determine your BMI and whether you are at a healthy weight for your height.

    2. Assessing weight loss progress: A body mass calculator can help you track your weight loss progress over time by calculating your body mass index (BMI) at regular intervals. This can help you determine if your weight loss efforts are effective and if any adjustments need to be made.

    3. Planning a weight loss program: A body mass calculator can help you determine your BMI and set weight loss goals. For example, if you are overweight, you may want to aim to lose a certain amount of weight to reach a healthy BMI.

Prices are based on a recurring monthly subscription depending on the plan selected — plus overage fees applied when a developer exceeds a plan’s quota limits.
