How do you measure 1cc on the needle?

To measure 1 cc (cubic centimeter) using a syringe, ensure you have a syringe marked in milliliters (mL), as 1 cc is equivalent to 1 mL. Pull the plunger back to the 1 mL mark, ensuring there are no air bubbles in the syringe. If you see air bubbles, gently tap the syringe to release them, then adjust the plunger to the 1 mL line again. Always check that the measurement is level with the line for accuracy.
