The Boyd formula is BSA = 3.207 (Height)
0.3
x (Weight x 1000)
(0.7285 – 0.0188 Log (Weight x 1000))

.5378
x Ht

and is displayed in milliliters. If the patient weight is greater than or equal to 20 kg,
the formula used is 70 mL x Wt (kg). If patient weight is greater than or equal to 10 kg
and less than 20 kg, the formula is 75 mL x Wt (kg). If the patient weight is less than
10 kg, the formula is 80 mL x Wt (kg).
