I need to convert one gallon an hour to ounces per second

Answer 1

gallon is volume, ounces is weight.

Perhaps you mean "fluid ounces", an obselete measure of volume.

1 gal/hr *1hr/3600sec * 128fluidoz/gal

Or, you can cheat and let google do it for you: Paste this in the google search window..
1gallon/hr in fluid ounces /second

Answer 2

1 gallon = 128 ounces

1 hour = 60 * 60 = 3600 seconds

128/3600 = ?
