About Units Per Hour (Insulin) Calculator

Converts a pump rate and syringe concentration into units per hour and checks it against the weight-based rate used in protocols.

Formula

Insulin delivery

Units per hour = concentration (units/mL) x pump rate (mL/h); units/kg/h = units per hour / weight

Worked example

With the default values below, Units Per Hour (Insulin) Calculator returns Insulin delivered of 3.000. Change any input above and every figure here is recalculated in your browser.

Inputs used

Syringe concentrationaccepts 0.1–10 units/mL: 1 units/mL
Pump rateaccepts 0.1–50 mL/h: 3 mL/h
Body weightaccepts 1–250 kg: 70 kg

Results

Insulin delivered: 3.000 units/h
Insulin per kilogram: 0.0429 units/kg/h
Insulin over 24 hours: 72.0 units

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 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

Frequently Asked Questions

What weight-based rate is standard?

0.1 units/kg/h is the usual fixed rate in diabetic ketoacidosis protocols.

Why 50 units in 50 mL?

It gives a 1 unit per mL concentration so the pump rate in mL/h equals the insulin rate in units/h.
