Total usage per month for the large part = 0.001979 gal/ ft2 x 750,000 ft2 = 1,484 gals of paint per month Small part paint usage per ft2 @ 1.2 mils = [(144 in2/ft2 x 0.001 in)/(35/100 x 231 in3/gal)]/90/100 x 1.2 mil = 0.002375gal/ft2 @ 1.2 mils Small part electrocoat usage per ft2 @ 1.0 mils = [[(144 in2/ft2 x 0.001in)/(35/100 x 231 in3/gal)]/90/100) x 1.0 mil =0.001979 gal/ft2 @ 1.0 mils Total paint usage per month for the small part @ 1.mils = 0.002375 gal/ft2 x 250,000 ft2 = 593.7 gals per month Total paint usage per month for the small part @ 1.0mils = 0.001979 gal/ft2 x 250,000 ft2 = 494.75 gals of coating per month If the small parts where coated at 1.0 mil instead of 1.2 mil the paint usage would be reduced about 100 gallons per month. To determine the percentage of the reduction divide 100 by the total usage. Usage per square foot is a valuable tool when determining costs and changes in costs. The calculations should be used to determine how much paint is used and how changes might effect costs. 823
