Carry out this task

  1. Open the linked tool and enter the displayed values.
  2. Compare the complete-load count with the exact dose amount.
  3. Choose Calculate & Save and compare the displayed result with the worked calculation.

Calculation and observed tool result

floor(25 ÷ 25) = 1 loads

Recorded quantity: 25 ml.

What the result means

Exactly one full load is available.

A mistake to avoid

Rounding the measured amount down prematurely can hide that final dose.

Limits of this example

Measurement uncertainty still matters near this boundary.
