How do I become a BSA?
Body Surface Area (BSA)
- Calculate weight in kilograms: 210 pounds ÷ 2.2 = 95.45 kg.
- Calculate height in centimeters: 6 feet, 3 inches = 75 inches x 2.54 cm/inch = 190.5 cm.
- Multiply height by weight and divide by 3600. (190.5 cm x 95.45 kg) ÷ 3600 = 5.
- Take the square root of 5 = 2.24 m2
