Weight is highly affected by the abnormalities in adipose tissue but however, body surface area BSA is usually known to be more effective because it does not depend upon the content or abnormality of adipose tissue in your body. It is probably not worth the trouble to debate about which formula may or may not be slightly better.

Aim: To explore the suitability of existing formulas to estimate the body surface area (BSA) of newborns when direct measurement of surface estimation is not practical. Body weight was the best single measure for predicting total area and regional areas, and little advantage was gained by using multiple regressions incorporating body weight, fat content and body dimensions. Thus covering a similar percentage of the newborn's body with a skin-absorbable substance will lead to a larger dose per unit of body weight compared with what an … After birth this excess water must be mobilized and excreted.
