How Much Is 12 Ounces of Tomato Sauce in Milliliters?
Converting 12 ounces of tomato sauce to milliliters gives 328.51 ml. First convert to grams (12 oz = 340.19g), then divide by the density of tomato sauce (245g per cup). Each ingredient fills a different volume at the same weight.
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.
Tomato Sauce at Different Amounts
How tomato sauce scales across common ounces measurements. Your amount (12 ounces) is highlighted.
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.
What is a Milliliter?
Most kitchen measuring cups outside the US are marked in milliliters. A standard metric cup is 250 ml. When converting American recipes, 1 US cup = 236.588 ml.
About 328.51 ml, based on tomato sauce having a density of 245g per cup. The exact amount depends on how the ingredient is measured and the specific product.
First convert ounces to grams (1 ounce = 28.3495g), then divide by 245 (grams per cup), then multiply by 236.588 to get milliliters. For 12 ounces: 12 × 28.3495 = 340.19g, then 340.19 ÷ 245 = 1.39 cups × 236.588 = 328.51 ml.
For the most accurate results, weigh tomato sauce 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 tomato sauce 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: 328.51 ml ÷ 236.588 = 1.38855 cups, then 1.38855 × 245g/cup = 340.19g, then 340.19g ÷ 28.3495 = 12 ounces. Or use the Milliliters to Ounces converter.
