Syringe Pump Rate Calculator

Work out syringe pump rate instantly with clear inputs, formula shown and shareable results.

About Syringe Pump Rate Calculator

Converts a microgram per kilogram per minute prescription into a syringe pump rate in millilitres per hour.

Formula

Pump rate

mL/h = dose (mcg/kg/min) x weight (kg) x 60 / concentration (mcg/mL)

Worked example

With the default values below, Syringe Pump Rate Calculator returns Syringe pump rate of 21.000. Change any input above and every figure here is recalculated in your browser.

Inputs used

Prescribed doseaccepts 0.01–100 mcg/kg/min: 5 mcg/kg/min
Body weightaccepts 0.5–250 kg: 70 kg

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 3 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

Why multiply by 60?

The dose is per minute and the pump is set per hour, so the per-minute delivery is scaled to an hour.

What if concentration is in mg/mL?

Multiply the mg/mL figure by 1000 to get mcg/mL before using it here.
