How Much Is 1.5 Quarts of Milk in Ounces?
1.5 quarts of milk weighs 51.64 oz. This is based on milk having a density of 244g per cup. Because quarts measure volume and ounces measure weight, the result depends on the ingredient, and a different ingredient would give a different result for the same 1.5 quarts.
Formula and Step-by-Step
- Start with 1.5 quarts of milk
- 1 quart of milk = 976g
- 1.5 × 976 = 1,464g
- Convert grams to ounces: 1,464 ÷ 28.3495 = 51.64 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.

Understanding the Units
What is a Quart?
The quart gets its name from "quarter" (of a gallon). One US quart is about 5.7% smaller than 1 liter (946 ml vs 1,000 ml). Always use the exact unit your recipe specifies.

An ounce (oz) is a US customary unit of weight equal to 28.3495 grams or 1/16 of a pound. In cooking, "ounces" refers to weight (avoirdupois ounces), not fluid ounces which measure volume.
