How many ounces does one cup sugar weigh?

Answer 1

It depends on the density of the sugar.

But:

1 cup = 8 fl oz

1 fl oz = 1/128 gal

1 gal = 231 in3

8 fl oz (1/128 gal/ fl oz) = .0625 gal

.0625 gal (231 in3/gal) = 14.437 in3

1 cup = 14.437 in3

Thus:

density of sugar [lb/in3] * 14.437 in3 = weight of sugar

And:

Bagged raw sugar = 42.4 lb/ft3

Bagged white sugar = 54.9 lb/ft3

Then:

42.4 lb/ft3 * (1/12 ft/in)3 * 14.437 in3 = .35 lb

54.9 lb/ft3 * (1/12 ft/in)3 * 14.437 in3 = .45 lb

And:

1 lb = 16 ounces

Finally:

.35 x 16 = 5.6 ounces

.45 x 16 = 7.2 ounces.

Answer 2

8 ounces are in a cup,so I would imagine that there is 16 ounces in 2 cups...unless dry measures differant than liquid???

Answer 3

One cup of sugar weighs approximately 7 to 8 ounces, depending on the type of sugar and how compacted it is.
