Tablet Dosing Calculators
Calculate the number of tablets to give from a prescribed dose in mg or a weight-based dose in mg/kg.
mg to Tablets Calculator
Convert a flat prescribed dose in mg into the number of tablets using tablet strength.
mg/kg to Tablets Calculator
Calculate tablets from a weight-based dose (mg/kg) and patient weight.
How tablet dosing calculations work
Tablet calculations follow a simple formula: divide the prescribed dose (mg) by the tablet strength (mg/tablet). The result tells you how many tablets to give.
For weight-based doses, first multiply the patient weight (kg) by the dose per kilogram (mg/kg) to get the total dose in mg, then divide by tablet strength.
Safety note: The mathematical result may not always be a whole or half tablet. Always check local policy on allowable rounding and whether a liquid formulation is more appropriate.
