Formulae & Calculation Steps

1
Weight Convert: lbs ÷ 2.205 = kg | grams ÷ 1000 = kg
2
Single Dose: Dose (mg/kg) × Weight (kg)
3
Daily Dose: Single Dose × Frequency per day
4
Syrup Volume: (Single Dose ÷ Concentration mg) × 5 mL
5
Injection Volume: Single Dose ÷ mg/mL
6
Tablets: Single Dose ÷ mg per tablet
7
IV Drip Rate: (Volume × Drop Factor) ÷ (Time hrs × 60)
8
CrCl: [(140 − Age) × Wt × Sex] ÷ (72 × SCr) | Female × 0.85
9
% Solution: % × 10 = mg/mL | e.g. 5% = 50 mg/mL
