I guess the bottom line is, I haven't the slightest idea how much volume your calculations equal. I don't know alot about ml. I do know I have flushed 21 times and have a volume of between 1 1/2 to 2 5-gallon buckets, however many mls. that might be. Sorry to sound so dumb.

I just checked the site that I got the information from it is states as follows:
Fluid Ounce 1/8 cup.
29.57352956 milliliters The fluid ounce is a unit of volume, not weight. It is equal to the volume of water which weighs one ounce at a specific temperature and pressure.
