**Where BSA is represented in m**

^{2}, W is weight in kg, and H is height in cm, the formulas are as follows:- Du Bois formula:
**BSA**= 0.007184 × W^{0.425}× H^{0.725} - Mosteller formula:
**BSA**= = 0.016667 × W^{0.5}× H^{0.5} - Haycock formula:
- Gehan and George formula:
- Boyd formula:
- Fujimoto formula:
- Takahira formula:
- Schlich formula:

Also know, how do you calculate body surface area for medication doses?

**References**

- Equation: BSA (m
^{2}) = 0.0235 x Height(cm)^{0.42246}x Weight(kg)^{0.5145}^{6} - Equation: BSA (m
^{2}) = 0.024265 x Height(cm)^{0.3964}x Weight(kg)^{0.5378} - Equation: BSA (m
^{2}) = SQR RT ( [Height(cm) x Weight(kg) ]/ 3600 )

Likewise, how do you find the surface area? **How to find the surface area of Rectangular Prisms:**

- Find the area of two sides (Length*Height)*2 sides.
- Find the area of adjacent sides (Width*Height)*2 sides.
- Find the area of ends (Length*Width)*2 ends.
- Add the three areas together to find the surface area.
- Example: The surface area of a rectangular prism 5 cm long, 3 cm.

Correspondingly, how is BSA DuBois calculated?

**Du Bois** D, **Du Bois** EF. A **formula** to estimate the approximate surface area if height and weight be known. Arch Intern Med. 1916; 17:863-871.

Parameter | LOINC's and Suggested Units |
---|---|

Height | 8302-2 : cm |

Weight | 29463-7 : kg 3141-9 : kg 8350-1 : kg 8351-9 : kg |

What does mg/m2 mean?

I assume this is for drug dosages, where some are specified as mg/kg (related to body mass), while some are specified as **mg/m2** (related to "body surface area" or BSA). So you need to find someone's BSA. There are several formulas, all of which take into account height in addition to mass.
