From Brew Cabin. "3/4 cup = 6oz."

From Howmany.wiki. "1.25 cups = 3.5 oz."

From Homebrew Talk. "3/4 of a cup is 4oz."

From American Homebrewers Association. "Papazian and Palmer and some folks on this blog have said that 3/4 cup (5.3 oz.) of corn sugar (or 5/8 cup of table sugar) is the correct amount to prime 5 gal. of beer for bottle carbonation."

So I've got 3/4 cup of corn sugar weights 6oz, 3.5oz, 4oz or 5.3oz.

There is no consistency. Does anyone actually know how many ounces of corn sugar I should use as primer for 5 gallons of beer? Or how many ounces of corn sugar are in a 3/4 cup? From what I'm seeing it appears that different brands of corn sugar must have different weights. Is that the problem. I'm very confused.
