Are there any formulas available to calculate BSA?
AllCalculator.net's Body surface area uses a formula by entering your height in centimetres and weight in kilograms to calculate the final BSA. The formulas are discussed below:
DuBois formula
This formula is widely used in medicine and was derived from a study using only nine individuals.
BSA = 0.007184 x weight0.425 x height0.725
Mosteller formula
This formula is used to compute BSA, which is simpler than the other body surface area formulas.
BSA = 0.016667 x weight0.5 x height0.5
Haycock formula
Using calculations, the DuBois formula underestimated BSA for values below 0.7 m2; nomograms helped develop the Haycock formula to compute BSA.
BSA = 0.024265 x weight0.5378 x height0.3964
Gehan and George's formula
This formula is used to derive using similar models as the DuBois formula.
BSA = 0.0235 x weight0.51456 x height0.42246
Boyd formula
It is also used to estimate body surface area based on a comprehensive comparison of various methods used to calculate BSA.
BSA = 0.033 x weight (0.6157 – 0.0188 x log10 (weight)) x height0.3
Fujimoto formula
It took body surface area from actual measurements of body weight and surface area on 201 Japanese from neonatal to old age and examined this data.
BSA = 0.008883 x weight0.444 x height0.663
Takahira formula
Takahira and colleagues developed a body surface area formula based on regional rates in Japan by age, sex and race.
BSA = 0.007241 x weight0.425 x height0.725
Shuter and Aslani formula
Shuter and Aslani derived the formula by revisiting the data from the original Dubois equation.
BSA = 0.00949 x weight0.434972 x height0.67844
Schlich formula
It was derived from Laser-supported body scanning to measure active heat exchange over the body surface.
BSA for women = 0.000975482 x weight0.46 x height1.08
BSA for men = 0.000579479 x weight0.38 x height1.24
What are the applications of BSA?
AllCalculator.net's Body surface area calculates the energy expenditure, also known as resting metabolic rate, when the rate is required per square meter per hour. It applies to total daily energy expenditure calculations. It is used to determine
- Dosage of medications
- To estimate renal clearance
- In chemotherapy dosage
- Glucocorticoid dosage
- Composition of the cardiac index.
- Even organ transplantation also uses the body surface area as an important metric.
The formula the calculator uses is as follows:Area = PI (3.141) * r ^2 * a/360Where r is that the radiusa is that the arc angle also referred to as the central angle.
(For a semi-circle this is often always 180 degrees)How to calculate the world of a semi-circleHere are some steps we have provided you to calculate the semi-circle.
If you’re trying manually then these processes will help you a lot.
We have provided the entire step you have to follow to calculate semi-circle but here we are when you need an online and a web-based calculator for you.Measure the AngleThe first step is to make sure that the world you're looking to calculate is actually a semi-circle.
If you are doing find this to be the case, the angle within the formula above are going to be 180 degrees.
For this instance, we are getting to assume the diameter of the semi-circle is given at 2 meters (m).
