Amount in US cups = 1
Or a weight to convert back = 100
Grams per cup used = 102 = 102
Weight = 1 * 102 = 102
Weight in ounces = 102 / 28.349523125 = 3.597 94
Tablespoons = 1 * 16 = 16
Teaspoons = 1 * 48 = 48
Volume = 1 * 236.5882365 = 236.588
Cups in the weight you entered = 102 > 0 ? 100 / 102 : 0 = 0.980 392
Tablespoons in that weight = 0.980 392 * 16 = 15.6863
Implied bulk density = 102 / 236.5882365 = 0.431 129

Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula

grams = cups x grams per cup
1 US cup = 16 tablespoons = 48 teaspoons = 236.588 236 5 mL exactly
1 ounce = 28.349 523 125 g exactly

Cup figures assume the spoon-and-level convention: fluff the ingredient, spoon it into the cup and sweep the top flat. Dipping the cup straight into the bag packs in up to 20% more.

The volume conversions on this page are exact by definition. Only the grams-per-cup figure is a measured convention, and it is stated above so you can substitute your own.
