This calculator uses the formula of Haycock et al, which has been validated for the whole paediatric and adult population including extremely low birth weight infants.
Input the child's weight (in kg) and his or her length (in cm).
Surface Area = W 0.5378 x L 0.3964 x 0.024265
The equation has two variables: weight in kg (W) , and length in cm (L).
