Pssst! It's me, the website.

I just wanted to let you know that even though I'm looking quite old, I'm still a millenial.
So I just had a "New Year, New Me" moment and my resolution is to become a new and improved version of myself in a couple of weeks.
Don't worry, my wisdom won't change. You're still going to find the same useful information here. Stay tuned!

 Body Surface Area Formula BSA(m2) = Dubois and Dubois : = 0.20247 x height (m) 0.725 x weight (kg) 0.425 Haycock : = 0.024265 x height (cm) 0.3964 x weight (kg) 0.5378 Gehan & George : = 0.0235 x height (cm) 0.42246 x weight (kg) 0.51456 Boyd : = 0.0003207 x height (cm) 0.3 x weight (g) 0.7285 - (0.0188 x log(weight(g))) Mosteller: = square root ( (height (cm) x weight (kg))/ 3600)

How to calculate a BSA.

Step 1: Obtain the weight and height of the patient. Enter the weight and height along with the unit values for the weight and height.  The formula listed above is used to calculate the Body Surface Area (BSA).

Check Normal Values by BSA
