How Much Is 15 Tablespoons of Onions (Diced) in Ounces?
15 tablespoons of onions (diced) weighs 5.29 oz. This is based on onions (diced) having a density of 160g per cup. Because tablespoons measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 15 tablespoons.
Formula and Step-by-Step
- Start with 15 tablespoons of onions (diced)
- 1 tablespoon of onions (diced) = 10g
- 15 × 10 = 150g
- Convert grams to ounces: 150 ÷ 28.3495 = 5.29 oz
The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.
Measuring Tip
The weight of diced produce per cup depends on how finely it is cut. Smaller dice packs more tightly and weighs more per cup than large chunks.
