Pediatric Dose Calculator

The pediatric dose calculator works out daily dosage and dosage from dose, frequency, mass, volume and weight of child. Enter what you have and the relationship is applied straight away, so you get the answer without working through the algebra yourself.

What Is the Pediatric Dose Calculator?

The pediatric dose calculator gives you an estimate of daily dosage and dosage based on dose, frequency, mass, volume and weight of child.

It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.

How the Pediatric Dose Estimate Is Worked Out

The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.

If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.

What This Calculator Does Not Do

It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.

A Worked Example

Working through an example, with dose set to 10, frequency set to 1, mass set to 5, the calculator returns dosage of 400, and dosage (mg kg dose) of 400, and dosage (mg day) of 4. Substitute your own figures and the same steps produce the same kind of answer.

Frequently Asked Questions

What do I need to work out daily dosage?

Enter dose, frequency, mass, volume and weight of child. The calculator then works through the relationship and reports daily dosage and dosage.

What does the pediatric dose actually calculate?

It takes dose, frequency, mass, volume and weight of child and converts them into daily dosage and dosage using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.

How should I enter dose?

Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.

Does anything you type get stored?

No. The whole calculation runs inside your browser, and nothing you enter is uploaded, logged or sent anywhere.

Do I have to fill in every field?

Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
