Reproduce de-identified, source-labelled dosing-weight × mg/kg arithmetic and an optional documented mg/mL division without creating or approving a medication order.
A quick decision brief for this specific tool
One de-identified record scope and reviewed input basis; the exact named dosing-weight record in kilograms; an explicitly per-administration, per-day or other documented mg/kg factor; and an optional paired concentration-label record plus mg/mL value
A source-preserving weight × factor amount on the selected basis and, only when a complete concentration pair is entered, a separate mg ÷ mg/mL volume arithmetic record
Multiply only the documented kilograms by the documented mg/kg factor and optionally divide that result by the entered positive mg/mL value; no medication, order, weight basis, safe range, maximum, frequency, route, product or administration action is generated
Choose your path
Reproduce one de-identified, source-labelled dosing-weight × mg/kg record and optional documented concentration division without creating, changing or approving a medication order.
Keep factor basis, goal units and optional concentration cancellation explicit without turning an exercise into clinical advice.
Choose the education basis, name the stated dosing-weight record, select the exact mg/kg basis and copy the exercise factor and optional concentration pair.
Can reconcile multiplication and division while seeing that the tool supplies no medication, safe range, schedule, route or administration action.
Avoid silently substituting a different weight, factor basis, formulation or concentration during an independent arithmetic check.
Use a de-identified verified-order or administration record and copy every basis label and value from the controlling sources.
Gets an auditable amount and optional volume record to compare with the order and exact product while clinical judgment and safeguards remain outside the tool.
Expose mg/kg/day versus mg/kg/administration and incomplete concentration-pair errors without a frequency what-if control.
Review source labels, run basis-specific examples and confirm that an unpaired concentration record is rejected.
Can trace every input and unit without a drug recommendation, maximum-dose claim, proportional chart or generated schedule.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.

Calculate a de-identified pediatric BMI and exact single-month-age percentile from the official CDC 2022 Extended BMI-for-Age parameters.
The record names the controlling dosing-weight definition and factor basis. It does not choose actual, ideal, adjusted or another weight, and it does not reinterpret mg/kg/day as mg/kg/administration or split a daily amount into a schedule.
Entered amount (mg on the selected basis) = documented dosing weight (kg) × documented factor (mg/kg)Volume appears only when both an exact concentration-label record and its positive mg/mL value are entered. The result does not select a product, formulation, route, measurement device or preparation method.
Volume arithmetic (mL) = entered amount (mg) ÷ documented concentration (mg/mL)FDA medication-error and prescribing-information resources and qualified clinical/pharmacy review control the medication, patient, indication, order, dose basis, limits, formulation, route, interactions and monitoring. This tool checks none of them.
Arithmetic reproduction ≠ safe or authorized medication useUpdated: August 2026
An entered 20 kg exercise weight × 5 mg/kg/administration equals 100 mg/administration arithmetic. A separately entered 20 mg/mL exercise label produces 5 mL arithmetic without prescribing or authorizing that amount.
When the source states mg/kg/day, select Per day. The product is labelled mg/day arithmetic and is not divided by a frequency the user did not document.
Leave both optional concentration fields blank to retain only weight × factor arithmetic. Supplying just a label or just a numeric concentration produces an error rather than an invented volume.
Select the exact factor basis from the controlling record. This tool preserves per-administration, per-day and other documented bases without splitting or scheduling them.
Provide the concentration label and mg/mL together, then reconcile the result with the verified order, current prescribing information, exact product, route, facility safeguards and qualified clinical/pharmacy review.
Use one de-identified verified-order, reviewed-administration or education record. Preserve the exact dosing-weight basis and whether the entered factor is per administration, per day or another documented basis. The tool never supplies a medication, factor, safe range, maximum, frequency split, route, formulation, rounding rule or administration action.
