Tablet / liquid converter

Convert a known total dose in mg into tablet, capsule, or liquid administration math. This tool is arithmetic support only. Verify available strengths, score lines, and final formulation choice before use.

Use it for

Turning a finished milligram dose into a practical tablet, capsule, or liquid amount to administer.

It calculates

Raw formulation conversion, practical rounding, and the delivered mg after that rounding step.

It does not decide

Which formulation is best, whether a tablet can really be split, or whether the rounded amount is appropriate for the clinical plan.

Input

Enter the formulation math

Start with the final dose in mg, then choose the formulation you actually have in front of you. Tablet split allowance is only used for tablet arithmetic.

Total dose Dose unit

Formulation type Strength / Concentration

Strength unit Tablet split allowance optional

Match the formulation type and printed strength to the exact product in hand before relying on the rounded administration amount.

Result

Administration result

Enter the total dose and selected formulation strength to convert the final administration amount.

Awaiting calculation

Confirm the total dose in mg before converting.
Select the exact formulation type you are using.
Use the product strength printed on the label or package.

Formula

Formula audit trail

The audit trail shows the raw formulation conversion first, then the practical rounding rule used for the selected dosage form.

1. Raw units = total dose divided by strength.

2. Tablet rounding follows the selected split rule using whole, half, or quarter-tablet increments.

3. Capsule rounding uses whole numbers only.

4. Liquid rounding uses a practical measurable increment while keeping the arithmetic visible.

Rounding is shown explicitly so the delivered dose can be compared against the target dose.

Calculation steps will appear here for verification.

Safety checks

Review before use

Arithmetic support only.
Verify available strengths, score lines, and formulation choice.
Confirm the rounded amount is practical to measure or dispense.

Basis

Basis and limits

Calculation basis: total-dose conversion into tablet counts, capsule counts, or liquid volume from a known strength or concentration.
What this page does: keeps the raw math, practical rounding step, and delivered mg visible in one place.
What still needs checking: actual product strength, tablet splitability, measurable liquid volume, and final formulation choice before use.

Worked example and practice

Use these compact cases to rehearse formulation math without turning the tool into a long teaching page.

Worked example

A prescription calls for 37.5 mg, and the product available is a 25 mg tablet with half-tablet splitting allowed.

Raw tablets = 37.5 / 25 = 1.5 tablets
Delivered dose = 1.5 x 25 = 37.5 mg

The arithmetic is exact here, but you still need to confirm the tablet can truly be halved.

Try this case

Estimate the liquid volume for a 12 mg dose using a 20 mg/mL product before revealing the answer.

Reveal the arithmetic

Raw volume = 12 / 20 = 0.6 mL
Delivered dose at 0.6 mL = 12 mg
