A dose number is useful only when its assumptions are clear. Steroid Conversion Calculator turns the selected medication details into the specific reference calculation implemented here, while keeping clinical prescribing separate from arithmetic.

What this calculator does

Steroid Conversion Calculator uses Hydrocortisone, Cortisone, Prednisone, Prednisolone, Triamcinolone, Methylprednisolone, and the remaining displayed fields to produce the corticosteroid equivalence used by this calculator. It only uses the fields shown in this calculator; it does not silently add tests, diagnoses, symptoms, or clinical variables that are absent from the interface. symmetric corticosteroid-equivalence fields using standard relative glucocorticoid potencies.

How to use it

Enter or select Hydrocortisone, Cortisone, Prednisone, Prednisolone, Triamcinolone, and the remaining displayed fields. Double-check the medication, route or formulation choices, weight/unit conversions, and concentration before relying on the output. If an input is unknown, it is better to leave the calculation unresolved than to invent a value.

How the calculation works

The engine converts all entered corticosteroid amounts to a hydrocortisone-equivalent total using its potency table: 20 mg hydrocortisone corresponds to 25 mg cortisone, 5 mg prednisone, 5 mg prednisolone, 4 mg triamcinolone, 4 mg methylprednisolone, or 0.75 mg dexamethasone/betamethasone. It then displays the equivalent amounts across the same table.

Example

Using the calculator’s prefilled demonstration values, the primary output is 20 mg hydrocortisone equivalent, labeled “Corticosteroid equivalence”; Cortisone is 25 mg and Prednisone is 5 mg. That sample is useful for checking the calculation path, but real interpretation should use verified measurements from the same clinical or study context.

How to interpret the result

Read corticosteroid equivalence as the output of the selected reference rule, not as proof that the medicine, formulation, route, schedule, or dose is appropriate for a particular person. The useful next step is to compare the arithmetic with the current order or label and patient-specific clinical factors.

Limitations and notes

Medication selection, indication, age, organ function, pregnancy, allergies, interactions, formulation, route, concentration, and current product labeling can all change safe use. Treat this result as reference arithmetic, not an instruction to start, stop, switch, or adjust a medicine without appropriate clinical review.
