if you need .74 ouce per 1,000 sq and i need to cover 17,000 sq ft. so how many gallon of water is needed.

i think i'm missing something also in my calculation

12.58 gallons I believe.

.74 x 17,000 = 12580 oz.

12580 oz. / 128 (per gal) = 98.3 gal

Right?

Is it .74oz per gallon/1000???? or .74 per 5 gallon/1000??? You are missing the gallon rate.

This should be .74 X 17......not 17,000. This will only give you amoung of chemical.

0.098 gallons

7. ### tiedemanLawnSite Fanaticfrom earthMessages: 8,745

you take the total ounces, which would be 12.58 and multiply by 0.00781 to get the number of gallons needed

Nine one hundreths of a gallon of water??!!

sorry, but that is what my pesticide appendix booklet say to do to convert ounces to gallons. Now to convert gallons to ounces you multiply it by 128.
