How Much Is 1.63 Ounces of Rice (Long Grain) in Cups?
1.63 ounces of rice (long grain) equals 0.25 cups. Rice (long grain) has a density of 185g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.
Formula and Step-by-Step
- Start with 1.63 ounces of rice (long grain)
- Convert ounces to grams: 1.63 × 28.35 = 46.21g
- 1 cup of rice (long grain) = 185g
- 46.21g ÷ 185g/cup = 0.25 cups
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
Different rice varieties have different densities. Short-grain rice packs more densely per cup than long-grain because the rounder grains fill gaps more efficiently.
