It most often is, depending on the fluid and the volume administered. Larger volumes are measured in litres.
You can measure fluids in beakers, graduated cylinders or liquid measuring glasses. It depends on what you're measuring and why.

Any fluid may be measured in centilitres.

Small boxes. Car engines (their cylinder capacity). Most fluids (drinks, for example) are labelled in millilitres or litres, although the conversion is simple: 1ml = 1 cm3.

To prevent dehydration.
An instrument for measuring the specific gravity of fluids; a form hydrometer.

Also, because burns dramatically deplete the body of fluids, replacement fluids are administered intravenously.
An IV bag works by using a tube connected to a needle inserted into a patient's vein to deliver fluids and medications directly into their bloodstream. The bag is hung above the patient, allowing gravity to help push the fluids into their body. The rate of flow can be controlled to ensure the right amount of fluids and medications are delivered.
