How the Medicine Calculator Works

The calculator uses four simple inputs to calculate medication dosage accurately.

1. Patient Weight (kg)

Enter the patient’s body weight in kilograms.

Examples:

• 12 kg
• 25 kg
• 65 kg

2. Dose per kg (mg/kg)

Enter the prescribed medicine dosage per kilogram of body weight.

Examples:

• 5 mg/kg
• 10 mg/kg
• 20 mg/kg

3. Frequency (Times per Day)

Enter how many times the medicine should be administered each day.

Examples:

• Once daily
• Twice daily
• Three times daily

4. Medicine Concentration (mg/ml)

Enter the concentration of the medicine solution.

Examples:

• 100 mg/ml
• 250 mg/ml
• 500 mg/ml

After entering the required information, the calculator instantly generates accurate dosage results.

Medicine Dosage Formula

The calculator automatically performs several dosage calculations.

Total Daily Dose

$\text{Total Daily Dose} = \text{Patient Weight} \times \text{Dose Per Kg} \times \text{Frequency}$Total Daily Dose=Patient Weight×Dose Per Kg×Frequency

Dose per Administration

$\text{Dose Per Administration} = \frac{\text{Total Daily Dose}}{\text{Frequency}}$Dose Per Administration=FrequencyTotal Daily Dose​

Volume per Administration

$\text{Volume Per Administration} = \frac{\text{Dose Per Administration}}{\text{Concentration}}$Volume Per Administration=ConcentrationDose Per Administration​

Total Daily Volume

$\text{Total Daily Volume} = \frac{\text{Total Daily Dose}}{\text{Concentration}}$Total Daily Volume=ConcentrationTotal Daily Dose​

These formulas help calculate medicine doses and liquid volumes accurately.

Example Medicine Dosage Calculation

Let’s understand the calculator with a practical example.

Suppose:

• Patient Weight = 15 kg
• Dose per kg = 12 mg/kg
• Frequency = 2 times daily
• Concentration = 150 mg/ml

The calculator will calculate:

Total Daily Dose

$15 \times 12 \times 2 = 360\text{ mg}$15×12×2=360 mg

Dose per Administration

$\frac{360}{2} = 180\text{ mg}$2360​=180 mg

Volume per Administration

$\frac{180}{150} = 1.2\text{ ml}$150180​=1.2 ml

Total Daily Volume

$\frac{360}{150} = 2.4\text{ ml}$150360​=2.4 ml

This example demonstrates how the calculator simplifies medicine dosage calculations.
