Enter the total daily dosage and the weight of the patient into the calculator to determine the dosage in milligrams per kilogram per day. This calculator can also evaluate any of the variables given the others are known.

## Mg/Kg/Day Formula

The following formula is used to calculate the dosage in milligrams per kilogram per day.

D = (T * W) / D

Variables:

- D is the dosage in milligrams per kilogram per day (mg/kg/day) T is the total daily dosage (mg) W is the weight of the patient (kg) D is the number of doses per day

To calculate the dosage in milligrams per kilogram per day, multiply the total daily dosage by the weight of the patient. Then divide the result by the number of doses per day.

## What is a Mg/Kg/Day?

Mg/Kg/Day is a unit of measurement often used in pharmacology and toxicology to indicate the dosage or exposure level of a substance. It stands for milligrams per kilogram per day. This means the amount of a substance (in milligrams) given or received per kilogram of body weight per day. It is used to standardize dosages or exposure levels based on body weight, allowing for more accurate comparisons and calculations.

## How to Calculate Mg/Kg/Day?

The following steps outline how to calculate the Mg/Kg/Day using the formula: D = (T * W) / D

- First, determine the total daily dosage (T) in milligrams (mg).
- Next, determine the weight of the patient (W) in kilograms (kg).
- Next, gather the formula from above = D = (T * W) / D.
- Finally, calculate the Mg/Kg/Day dosage (D).
- After inserting the variables and calculating the result, check your answer with the calculator above.

**Example Problem : **

Use the following variables as an example problem to test your knowledge.

Total daily dosage (T) = 500 mg

Weight of the patient (W) = 70 kg

Number of doses per day (D) = 3
