To calculate the millilitres/hour we first need to work out what dose is contained in one millilitre of the infusion dosage. We can do this by dividing the volume of the dosage by the weight of the medicine it contains. In this case 500ml/500mg = 1ml/mg.

**How do you calculate drugs per kg?**

Care must be taken to properly convert body weight from pounds to kilograms (1 kg= 2.2 lb) before calculating doses based on body weight….Example 2.

Step 1. Calculate the dose in mg: | 18 kg × 100 mg/kg/day = 1800 mg/day |
---|---|

Step 3. Convert the mg dose to mL: | 1800 mg/dose ÷ 40 mg/mL = 45 mL once daily |
