Solution 1 liter = 1000 mL. Set up the conversion so the desired unit will be canceled out. In this case, we want mL to be the remaining unit. Volume in mL = (Volume in L) x (1000 mL/1 L) Volume in mL = 5.0 L x (1000 mL/1 L) Volume in mL = 5000 mL. Howmany milliliters in 5.2 liters? 5 1/5 liters equals 5200 milliliters. To convert any value in liters to milliliters, just multiply the value in liters by the conversion factor 1000. So, 5.2 liters times 1000 is equal to 5200 milliliters. Tocalculate a liter value to the corresponding value in milliliter, just multiply the quantity in liter by 1000 (the conversion factor). Here is the formula: 9 1 / 5 liters = 9200 milliliters: 9.3 liters = 9300 milliliters: 9.4 liters = 9400 milliliters: Note: some values may be rounded. Sample Volume Conversions. Onemilliliter is equal to 1 cubic centimeter (cm 3), 1/1,000,000 cubic meters (m 3), or 1/1000 liters. History/Origin: The base unit of the milliliter is the liter (US spelling), spelled "litre" in SI terms. The term "litre" was originally part of the French metric system and was derived from the term "litron," one of the older versions of the rqEHuM.
