What is Body Surface Area?

Body Surface Area (BSA) is a measurement used to calculate the total surface area of a human body. It is used to determine the amount of medication or other treatments needed for a person, as well as to calculate the metabolic rate of a person. BSA is calculated by using a mathematical formula that takes into account a person’s height and weight.

What is Body Surface Area Calculator?

A body surface area calculator is a tool used to estimate the total surface area of a person’s body. It is used to calculate the amount of medication needed for a patient, as well as to measure the effectiveness of treatments. It is also used in medical research to compare the body surface area of different individuals.

How to Calculate Body Surface Area?

The most commonly used formula to calculate body surface area is the Mosteller formula. This formula is as follows: BSA (m2) = SQRT( [Weight (kg) x Height (cm)] / 3600 ) For example, if a person weighs 70 kg and is 180 cm tall, the calculation would be: BSA (m2) = SQRT( [70 x 180] / 3600 ) BSA (m2) = 1.86 m2
