Notes
  • The formula depicted, which is based on gender, total body weight, and height, can be used to estimate LBW for adult males who are of normal weight or obese.
  • This calculation is not applicable to individuals with abnormal body water composition (eg, fluid overload).
  • This calculator is not validated in individuals at extremes of height, in those with highly muscular builds, or in underweight individuals.
  • The equation on which the calculator was based was derived from data on a population of individuals with bodyweights up to 216.5 kg or body mass index (BMI) up to 69.9 kg/m2 but was not validated in individuals weighing greater than 131.7 kg or with BMI over 38.4 kg/m2.
  • A separate calculator is available for estimating ideal body weight (method of Devine) and adjusted dosing weight.

 
Equations used
 
BMI[kg/m2] = Total_body_weight[kg] / sq(Height[cm] / 100)
LBW[kg] = (9270 * Total_body_weight[kg]) / (6680 + (216 * BMI[kg/m2]))

 

 
Only digits 0 to 9 and a single decimal point (".") are acceptable as numeric inputs. Attempted input of other characters into a numeric field may lead to an incorrect result.
