9. Volumes. We will work with liters (L) and milliliters (mL) in this class. We will work with liters (L) and milliliters (mL) in this class. 1000 mL = 1L; 1000 L = 1 m 3 1000 mL = 1L; 1000 L = 1 m 3 Cubic centimeters (cm 3 ) and milliliters (mL) are different names for the same amount. 1 mL = 1 cm 3. Cubic centimeters (cm 3 ) and milliliters (mL) are different names for the same amount. 1 mL = 1 cm 3. 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL. 1 drop from a dropper is approximately 0.05 mL. So, 20 drops = 1 mL.
