the ADA classification ranges for information.Body Surface Area CalculatorEstimates body surface area in m² from height and weight by the Mosteller, Du Bois, Haycock and Gehan-George equations, showing all four side by side with the spread between them and the ratio to the standard 1.73 m².Dosage Calculations CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.Absolute Count CalculatorAbsolute neutrophil count from the WBC and the segs and bands percentages (or from absolute differential counts), graded by NCI CTCAE v5.0 and the mild/moderate/severe clinical scale.Meld Score CalculatorComputes the MELD, MELD-Na and MELD 3.0 scores for chronic liver disease from bilirubin, INR, creatinine, sodium and albumin, applying the published laboratory floors, the creatinine ceiling and the dialysis rule, and reports the three-month waiting-list mortality band for the score.Revised Cardiac Risk Index CalculatorScores perioperative cardiac risk before non-cardiac surgery by the Revised Cardiac Risk Index of Lee et al., reporting both the original 1999 validation-cohort event rates and the CCS 2017 pooled estimates, and by the original 1977 Goldman multifactorial index with its class and published complication rate.Dosage Tylenol CalculatorReads the acetaminophen dose for a child's weight straight from the AAP dosing chart or the Infants'/Children's TYLENOL Drug Facts label, with the concentration, dosing interval and 24-hour ceiling, and also does prescriber-directed mg/kg and mg/m² arithmetic.Pet Nutrition Alliance Calorie CalculatorCalculates a dog or cat's resting and daily maintenance energy requirement from body weight and life stage, and converts the result into a daily food portion.Cha2ds2 Vasc CalculatorScores stroke risk in non-valvular atrial fibrillation by CHA2DS2-VASc, CHADS2 or the 2024 ESC CHA2DS2-VA, itemises which criteria contributed, and reports the published annual stroke rate for that score together with the cohort it came from.Dog Diet CalculatorCalculates a dog or cat's resting and daily maintenance energy requirement from body weight and life stage, and converts the result into a daily food portion.Dog Feed CalculatorCalculates a dog or cat's resting and daily maintenance energy requirement from body weight and life stage, and converts the result into a daily food portion.mg Convert mL CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.mg mL CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.mg Into mL CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.Calorie Cats CalculatorCalculates a dog or cat's resting and daily maintenance energy requirement from body weight and life stage, and converts the result into a daily food portion.Gfr Kidney Foundation CalculatorEstimates glomerular filtration rate in mL/min/1.73 m² by the CKD-EPI 2021 creatinine, creatinine-cystatin C, CKD-EPI 2012 cystatin C, IDMS MDRD or bedside Schwartz equation, with the KDIGO GFR category.Reconstitution CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.Tirzepatide Dosage CalculatorConverts between drug mass, solution concentration and volume: desired-over-have, mg to mL, mg/kg and mg/m² dosing, reconstitution, tablets per dose, days supply, mg/kg maximum dose and titration schedules.Arterial Blood Gas CalculatorInterprets an arterial blood gas: identifies the primary acid-base disorder, computes the expected compensation and flags a superimposed second disorder, calculates the anion gap with albumin correction and the delta-delta, and works the alveolar gas equation, A-a difference, P/F ratio, arterial oxygen content and oxygenation index.Childs Pugh CalculatorScores the severity of cirrhosis from bilirubin, albumin, INR, ascites and hepatic encephalopathy, gives the Child-Pugh class A, B or C with the conventionally reported survival figures, and supports the cholestatic bilirubin bands used in PBC and PSC.Goldman Risk Index CalculatorScores perioperative cardiac risk before non-cardiac surgery by the Revised Cardiac Risk Index of Lee et al., reporting both the original 1999 validation-cohort event rates and the CCS 2017 pooled estimates, and by the original 1977 Goldman multifactorial index with its class and published complication rate.mL Converted mg CalculatorConverts between drug mass, solution concentration and
