Learning outcomes

What you will learn

  • read mg/kg, mL/hr and similar units as “for each”
  • identify how many units the question gives you
  • multiply a per-unit amount to find the total
  • use the units to check what your answer represents
  • apply the same method when decimals are involved

Clinical connection

Why this matters

This is the maths behind weight-based doses, volumes delivered over time and repeated doses. Once you understand the “for each” idea, the calculation becomes much easier to recognise.
