Calculation Toolsa Measurement in Units
For adults 20 years old and older, BMI is interpreted using standard weight status categories that are the same for all ages and for both men and women.
For children and teens, on the other hand, the interpretation of BMI is both age- and sex-specific. For more information about interpretation for children and teens, visit Child and Teen BMI Calculator.

BMI is calculated the same way for both adults and children. The calculation is based on the following formulasc
Formula: weight (kg) / [height (m)]2 With the metric system, the formula for BMI is weight in kilograms divided by height in meters squared. Since height is commonly measured in centimeters, divide height in centimeters by 100 to obtain height in meters. Example: Weight = 68 kg, Height = 165 cm (1.65 m) Calculation: 68 ÷ (1.65)2
= 24.98 Pounds and inches Formula: weight (lb) / [height (in)]2
Calculate BMI by dividing weight in pounds (lb) by height in inches (in) squared and multiplying by a conversion factor of 703. Example: Weight = 150 lb, Height = 5'5" (65") Calculation: [150 ÷ (65)2
× 703 ] × 703 = 24.96 b c
NOTE: For adults, a BMI of 25.0 to 29.9 is considered overweight and a BMI of 30.0 is considered obese.
NOTE: Make sure you've selected the right options so that this calculator uses the formulas you intend/need to use for your patient's clinical situation. Note that because all present carboplatin dosing formulas are critically dependent on a measured or estimated value for renal function, and since dialysis patients (ie, patients with end-stage kidney disease) do not have any (significant) renal function, none of the formulas in this calculator is appropriate for such patients; do NOT use this calculator for such patients, period! Also, regardless of what dose is calculated, always remember to check whether prior carboplatin dosing for this patient was adjusted from a formula-derived dose due to clinical situations/ consequences such as prior severe cytopenias, or whether such situations have created a need to adjust subsequent dosing. Do NOT prescribe the calculated dose without first thinking about whether that dose makes sense for that patient. Do NOT make your patient suffer because you will not take the time to think about the appropriateness of the dose you are prescribing. You have been warned! The treating physician is solely responsible for dosing errors due to use of formulas that are incorrect for the patient's clinical situation.
