Formula and Step-by-Step

quarts × 946.36g/qt ÷ 28.3495g/oz = ounces
  1. Start with 0.21 quarts of water
  2. 1 quart of water = 946.36g
  3. 0.21 × 946.36 = 198.74g
  4. Convert grams to ounces: 198.74 ÷ 28.3495 = 7.01 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 7.01 oz, based on water having a density of 236.59g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of quarts by 946.36 (grams per quart for water), then divide by 28.3495 to convert grams to ounces. For 0.21 quarts: 0.21 × 946.36 = 198.74g, then 198.74 ÷ 28.3495 = 7.01 oz.
For the most accurate results, weigh water 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 water changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
