That's an easy number to work with, so let's use it. 20 drops/milliliter = 20,000 drops/liter =1,000,000 drops / 50 liters. That means one part per million is the same as one drop of a substance in a million drops, or 50 liters, of water.
To find out how many cups in liters, multiply the liter value by the conversion factor or use the converter. 1 Liter = 4.2267528377 Cups [US] 1 Liter = 4 Cups [Metric] There are 4.2 cups in a liter, because one cup equals to 236.5 milliliters (mL) and one liter is 1000 mL, that makes 1000 / 236.5 = 4.22 cups in a liter. For example, to find out how many cups there are in a liter and a half of water, multiply the liter value by the conversion factor, that makes 0.5 * 4.22 = 2.1 US cups in a liter. Liter is a metric volume unit and equals to 4.2 US cups, 4 metric cups, 33.8 fl. ounces and 1000 mL.
