What is a cubic centimeter (cc)?
Cubic centimeter, often abbreviated as cc, is a metric unit of volume equal to one milliliter (mL). The centimeter is one hundredth of a meter. A cubic centimeter is the volume occupied by a cube that measures 1 cm on each side.
Some key facts about the cc:
- 1 cc = 1 mL
- 1 cc of water occupies a space of 1 cm x 1 cm x 1 cm
- 1 cc has a volume of 0.001 liters
- 1 cc is the same as approximately 0.034 fluid ounces
The cc is commonly used for measuring liquid volumes in medicine. Other metric units like liters and milliliters are used as well.
Many syringes for injections are calibrated in 0.1 cc or 1 cc increments. IV bags and tubing are also measured in cc’s. Using the metric system provides standardized dosing and fluid volumes across healthcare settings.
Why cc’s are used in medicine
There are several key reasons that cubic centimeters are utilized in healthcare:
- Metric system – The cc is part of the metric system which is universally used in healthcare for precise measurements.
- SI units – cc’s are an SI (International System) unit. Healthcare uses SI units for consistency.
- Ease of conversion – cc’s convert neatly to other metric volumes like liters and mL.
- Accuracy – cc’s allow very precise measurement of fluid volumes.
- Standard dosing increments – Many injections and IVs use standard cc doses, like 1 cc, 5 cc, etc.
The cubic centimeter’s utility for precisely measuring liquid medication volumes makes it an indispensable unit in healthcare.

How to measure 30 cc
Whether you need to measure out 30 cc of a medication, normal saline, or another liquid, accuracy is vital. Here are some step-by-step tips to precisely measure a 30 cc volume:
Using a 30 cc syringe
- Gather a 30 cc syringe and the medication vial.
- Pull the syringe plunger back to the 30 cc mark on the barrel. This draws air into the syringe.
- Insert the syringe tip into the vial. Push the plunger all the way in to push 30 cc of air into the vial.
- Turn the vial upside down. Pull back on the plunger until the medication reaches the 30 cc line.
- Double check the correct volume is drawn up. Tap out air bubbles. expel any excess med back into the vial.
- Remove any air in the syringe by gently tapping it with the needle pointed up and pushing the plunger to the 30 cc mark again.
Always verify the correct volume visually by seeing the fluid level at the 30 cc line on the syringe.
Using an IV bag
- Start with an empty IV bag designed to hold a volume of at least 30 cc more than needed.
- Draw up the desired medication into a syringe, in the amount to be added to the IV bag.
- Cleanse the injection port on the IV bag thoroughly with an alcohol wipe.
- Inject the medication through the port into the IV bag.
- Gently mix the medication and fluids. Check the volume added.
- Label the IV bag clearly with the contents, amount, and date added.
Always double check your work to ensure the correct volume of medication was added.
Using a graduated cylinder
- Obtain a glass graduated cylinder marked with cc measurements.
- Hold the cylinder upright on a flat surface.
- Carefully pour the liquid medication or solution into the cylinder, up to the 30 cc line.
- Read the meniscus at eye level for an accurate reading.
