1500 units is how many ccs?

To convert units to cubic centimeters (cc), you need to know the specific conversion factor for the units being used, as "units" can refer to different measurements in various contexts. However, if you're referring to milliliters (mL), 1 unit is typically equivalent to 1 mL, which means 1500 units would be equal to 1500 cc. If you're referring to something else, please specify the type of units for an accurate conversion.
