FAQs for Body Surface Area Calculator

What is a Body Surface Area Calculator?
A Body Surface Area Calculator is a tool used in medicine to estimate the total external surface area of the human body, often employed to determine drug dosages and assess metabolic functions.
What is the normal range for BSA?
The "normal" body surface area is generally taken to be 1.7 m2 but, in actual fact, the body surface area depends on more than just height and weight. Other influential factors include the age and gender of the individual. For example: Average body surface area for adult men: 1.9 m2.
How do you measure BSA?
The body surface area (BSA) of any adult, when derived from the arithmetic mean of the different values calculated from four independent accepted formulae, can be expressed accurately in Systeme International d'Unites (SI) units by the simple equation BSA = 1/6(WH)0.5,
What unit is BSA measured in?
In the following formulae, BSA is expressed in m2, weight (or, more properly, mass) W in kg, and height H in cm. The most widely used is the Du Bois formula, 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.
What is BSA in vital signs?
Body Surface Area (BSA) measures the total surface area of a person's body and is frequently used in order to calculate drug dosage.
