Formula and Step-by-Step

cups × 244g/cup ÷ 28.3495g/oz = ounces
  1. Start with 2 cups of milk
  2. 1 cup of milk = 244g
  3. 2 × 244 = 488g
  4. Convert grams to ounces: 488 ÷ 28.3495 = 17.21 oz

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

For liquids, place your measuring cup on a flat surface and read at eye level. The bottom of the meniscus (the curve at the surface) should align with the measurement line.

Frequently Asked Questions

About 17.21 oz, based on milk having a density of 244g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of cups by 244 (grams per cup for milk), then divide by 28.3495 to convert grams to ounces. For 2 cups: 2 × 244 = 488g, then 488 ÷ 28.3495 = 17.21 oz.
For the most accurate results, weigh milk on a kitchen scale. If measuring by volume, use a liquid measuring cup on a flat surface and read the level at eye height.
Temperature has a minimal effect on most cooking liquids. The density of milk changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
Reverse the conversion: 17.21 oz × 28.3495 = 488g, then 488g ÷ 244 = 2 cups. Or use the Ounces to Cups converter.
