How Much Is 1.59 Ounces of Rolled Oats in Cups?
Converting 1.59 ounces of rolled oats to cups gives 0.50 cups. First convert to grams (1.59 oz = 45.08g), then divide by the density of rolled oats (90g per cup). Each ingredient fills a different volume at the same weight.
Formula and Step-by-Step
- Start with 1.59 ounces of rolled oats
- Convert ounces to grams: 1.59 × 28.35 = 45.08g
- 1 cup of rolled oats = 90g
- 45.08g ÷ 90g/cup = 0.50 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Oats come in multiple forms (rolled, steel-cut, instant) that have different densities. Steel-cut oats are nearly twice as heavy per cup as rolled oats.

Understanding the Units
What is an Ounce?
Weight ounces and fluid ounces are different measurements. A fluid ounce measures volume (29.574 ml), while an ounce measures weight (28.35g). They only align for water, where 1 fl oz weighs approximately 1 oz.
What is a Cup?
In US cooking, a cup measures volume, not weight. One standard US cup holds 236.588 ml of liquid. Because different ingredients have different densities, a cup of one ingredient can weigh very differently from a cup of another.
