A body fat percentage calculator with caliper is a device used to measure the thickness of subcutaneous fat under the skin using calipers. It is a non-invasive method to estimate body fat percentage. An example of such a calculator is the handheld skinfold caliper, which has two jaws that are pressed against the skin to measure the thickness of the subcutaneous fat layer.
Body fat percentage calculators with calipers are important because they provide a relatively simple and inexpensive way to measure body fat percentage. They are also portable and can be used in a variety of settings, making them suitable for use in both clinical and research settings. One of the key historical developments in the use of body fat percentage calculators with calipers was the development of the Jackson-Pollock 3-site equation, which uses measurements from three different body sites to estimate body fat percentage.
