A body fat percentage (BF%) calculator without neck and waist measurements is a tool used to approximate the percentage of body fat based on height and weight. An example of such a calculator might be one that employs the Jackson and Pollock formulas.
These types of calculators have gained popularity due to their accessibility and as a complement to other BF% measurement techniques, often used by individuals seeking body composition assessments for fitness or medical purposes. Historically, the Jackson and Pollock formulas were developed and refined in the 1970s and 1980s, contributing to the advancement of BF% estimation methods.
