150 grams of buttermilk equals 0.15 qt. Buttermilk has a density of 245g per cup. A lighter ingredient like flour (125g/cup) would fill more volume at the same weight, which is why ingredient-specific conversions matter.

Formula and Step-by-Step
grams ÷ 245g/cup × 0.25 = quarts
Start with 150 grams of buttermilk
1 cup of buttermilk = 245g
150g ÷ 245g/cup = 0.61 cups × 0.25 = 0.15 quarts
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.
Buttermilk at Different Amounts
How buttermilk scales across common grams measurements. Your amount (150 grams) is highlighted.
A gram (g) is a metric unit of mass equal to 1/1000 of a kilogram. It is the standard weight measurement for precise baking worldwide. Professional bakers prefer grams because they are more accurate than volume measurements.
What is a Quart?
A US quart equals 946.353 ml, 4 cups, 2 pints, or 32 fluid ounces. It is commonly used for larger liquid quantities like broth, stock, and milk.
About 0.15 qt, based on buttermilk having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Divide the grams by 245 (grams per cup) to get cups, then multiply by 0.25 to get quarts. For 150 grams: 150 ÷ 245 = 0.61 cups × 0.25 = 0.15 qt.
For the most accurate results, weigh buttermilk 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 buttermilk 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: 0.15 qt ÷ 0.25 = 0.612245 cups, then 0.612245 × 245g/cup = 150g. Or use the Quarts to Grams converter.
