BSA Calculator

यह बीएसए कैलक्यूलेटर शरीर की सतह क्षेत्र का अनुमान 5 अलग-अलग फ़ार्मुलों से करता है।

The BSA Calculator estimates body surface area based on age, gender, height and weight by 5 different formulas.

The five methods to calculate BSA

Body surface area represents the total surface of the human body and its determination has several applications in medicine such as IV fluid measurements and drug dosage.

There are several estimation formulas available for use, the most common one being that published by Mosteller in 1987.

Mosteller’s formula

BSA = (((Height in cm) * (Weight in kg))/ 3600)^½

Boyd’s formula

BSA = 0.0003207 * ((Height in cm)^0.3) * ((Weight in gm)^(0.7285 - ( 0.0188 x Log(grams)))

DuBois’s formula

BSA = 0.007184 * ((Height in cm)^0.725) * ((Weight in kg)^0.425)

Gehan & George’s formula

BSA = 0.0235 * ((Height in cm)^42246) * ((Weight in kg)^0.51456)

Haycock’s formula:

BSA = 0.024265 * ((Height in cm)^3964) * ((Weight in kg)^0.5378)
