The VOC requirements I read about are expressed grams per liter, but I buy paint in gallons. How do I know if I’m in compliance?

Simply divide the grams per liter amount by 120 to determine the pounds per gallon figure. For instance, a product that has a VOC of 250 grams per liter would have 2.08 pounds per gallon, because 250/120 = 2.08. To convert from pounds per gallon to grams per liter, multiply the number of pounds by 120.
