How Much Is 1.5 Quarts of Molasses in Ounces?

1.5 quarts of molasses weighs 71.96 oz. This is based on molasses having a density of 340g 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

quarts × 1,360g/qt ÷ 28.3495g/oz = ounces
  1. Start with 1.5 quarts of molasses
  2. 1 quart of molasses = 1,360g
  3. 1.5 × 1,360 = 2,040g
  4. Convert grams to ounces: 2,040 ÷ 28.3495 = 71.96 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.

What is an Ounce?

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.

Frequently Asked Questions

About 71.96 oz, based on molasses having a density of 340g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of quarts by 1,360 (grams per quart for molasses), then divide by 28.3495 to convert grams to ounces. For 1.5 quarts: 1.5 × 1,360 = 2,040g, then 2,040 ÷ 28.3495 = 71.96 oz.
Weighing molasses on a kitchen scale is strongly recommended. It is thick and sticky, so it clings to measuring vessels. If you must measure by volume, lightly oil the measuring cup first so it slides out cleanly.
Temperature has a minimal effect on most cooking liquids. The density of molasses changes slightly with temperature, but the difference is usually less than 1-2% between refrigerator and room temperature. This conversion assumes room temperature.
