【How-to】How much is 1 ml in a syringe

For instance, your syringe may be marked with a number at every successive mL. In between you’ll see a mid-sized line that marks half mL units, like 0.5 milliliters (0.02 fl oz), 1.5 mL, 2.5 mL, and so on. The 4 smaller lines between every half mL and mL line each mark 0.1 mL.
