  2. Body roundness index - Wikipedia

    en.wikipedia.org/wiki/Body_roundness_index

    Introduced in 2013, the BRI calculation can be used to estimate total and visceral body fat. Ranges of healthy body roundness have been established to accurately classify people with healthy fat mass ( weight ) compared to obese people who are at risk for morbidities .

  3. Body surface area - Wikipedia

    In the following formulae, BSA is expressed in m 2, weight (or, more properly, mass) W in kg, and height H in cm. The most widely used is the Du Bois formula, [4] [5] which has been shown to be equally as effective in estimating body fat in obese and non-obese patients, something the Body mass index fails to do.

    Clark's rule is a medical term referring to a mathematical formula used to calculate the proper dosage of medicine for children aged 2–17 based on the weight of the patient and the appropriate adult dose. [1] The formula was named after Cecil Belfield Clarke (1894–1970), a Barbadian physician who practiced throughout the UK, the West Indies ...

    The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...

  9. Weight function - Wikipedia

    en.wikipedia.org/wiki/Weight_function

    A weight function is a mathematical device used when performing a sum, integral, or average to give some elements more "weight" or influence on the result than other elements in the same set. The result of this application of a weight function is a weighted sum or weighted average .
