This is a list of units of measurement based on human body parts or the attributes and abilities of humans (anthropometric units). It does not include derived units further unless they are also themselves human-based. These units are thus considered to be human scale and anthropocentric.
The Corpulence Index (CI) (also Ponderal Index (PI) or Rohrer's Index) is a measure of corpulence, or of leanness in other variants, of a person [1] calculated as a relationship between mass and height. [2] It was first proposed in 1921 as the "Corpulence measure" by Swiss physician Fritz Rohrer [3] [4] and hence is also known as Rohrer's Index ...
The BRI models the human body shape as an ellipse (an oval), with the intent to relate body girth with height to determine body roundness. A simple tape measure suffices to obtain waist circumference and height. [1] [2] Waist circumference and height can be in any unit of length, as long as they both use the same one. [1] [3
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured. Many of these are redundant, in the sense that they obey a known relationship with other physical ...
The Body Roundness Index is similar to the Body Mass Index, but relies on more anthropometric variables. The BRI which was first proposed in 2013 , uses height, weight, waist circumference, and ...
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter.It appears in many formulae across mathematics and physics, and some of these formulae are commonly used for defining π, to avoid relying on the definition of the length of a curve.
Units of measure based on the human body or attributes/abilities of a human (e.g. inch). This does not include units further derived from these units (e.g. rod) unless they are also human-based (e.g. foot).
The ratio of the AC component to the DC component, expressed as a percentage, is known as the (peripheral) perfusion index (Pi) for a pulse, and typically has a range of 0.02% to 20%. [43] An earlier measurement called the pulse oximetry plethysmographic (POP) only measures the "AC" component, and is derived manually from monitor pixels. [41] [44]
