This free body surface area calculator estimates the surface area of a person's body based on body weight and height. Compare the results of various prevalent formulas, or explore hundreds of other calculators addressing fitness, health, finance, math, and more.
In physiology and medicine, the body surface area (BSA) is the measured or calculated surface area of a human body. For many clinical purposes, BSA is a better indicator of metabolic mass than body weight because it is less affected by abnormal adipose mass. Nevertheless, there have been several important critiques of the use of BSA in determining the dosage of medications with a narrow therapeutic index, such as chemotherapy.
Area averaging pressure results in summing the forces and dividing by the total area, ie area averaged pressure is is the same as total force over total area. On the other hand, a flow quantity such as Total Pressure or Enthalpy is not spacially conserved. If you need an average of these, you must take the mass_average.

Average body surface area for children (12-13 years): 1.33 m2 Body surface area is used for a determining other medical measures. As examples, renal function is measured by the glomerular filtration rate (GFR) which is calculated in regard to the body surface area.
Dear friend, U use area weighted avg. when ever u r using incompressible flow. The reason is that the density of the fuild is constant from inlet to outlet and hence area weigh. avg. will do. But for incompressible flow the density vary with temp and pressure and hence during that time u should used mass weight avg.
Because most walls are square or rectangular, you can determine their surface area by multiplying the width and height measurements and then subtracting any door or window space. Atypical architecture and design, however, can result in having triangular, circular or
room length 8ft,width 8ft,height 8ft. Do not use decimal numbers for the feet. Convert the measurements to all inches for first step, and then convert back to square feet for next step. Record dimensions with appropriate formula, find surface area
2010-01-27· Geometric method for measuring body surface area: A height weight formula validated in infants, children and adults. The Journal of Pediatrics 1978 (93):1:62-66. Gehan EA, George SL. Estimation of human body surface area from height and weight. Cancer Chemother Rep 1970 54:225-35. Boyd E. The growth of the surface area of the human body.
The surface area of adults is about 18,000 cm 2 (men) or 16,000 cm 2 (women). 1.6–1.8 m 2: Davis, F.A. Tabler's Cyclopedic Medical Dictionary. F.A. Davis Company, 1993. "The surface area may be calculated by multiplying 0.007184 times the weight in kilograms raised to the 0.425 power and the height in centimeters raised to the 0.725 power."
This online calculator computes pressure, cause by given mass over given surface in gravity field. According to wikipedia pressure is the force per unit area applied in a direction perpendicular to the surface of an object.. Mathematically. or. In gravity field the force is created by the weight of an object., where g is gravity acceleration, meter per square second.
2020-05-08· The surface area of a sphere is given by the formula Where r is the radius of the sphere. In the figure above, drag the orange dot to change the radius of the sphere and note how the formula is used to calculate the surface area. This formula was discovered over two thousand years ago by the Greek philosopher Archemedes.
2015-03-14· A high surface area to volume ratio, allows objects to diffuse nutrients and heat at a high rate. You will often see small mammals shirving constantly, because they are quickly loosing body heat to the enviroment and need to generate more heat to survive. This is also why we have over 1,000,000 small cells, instead of 5 large cells.
