Formula and Step-by-Step

(ounces × 28.35g/oz) ÷ 238g/cup × 236.588 = milliliters
  1. Start with 12 ounces of heavy cream
  2. Convert ounces to grams: 12 × 28.35 = 340.19g
  3. 1 cup of heavy cream = 238g
  4. 340.19g ÷ 238g/cup = 1.43 cups × 236.588 = 338.18 milliliters

The same formula works for any amount. Multiply (or divide) by the density, then convert units as needed.

Measuring Tip

Liquid densities vary: oils weigh less per cup than water, while syrups and honey weigh more. This is why ingredient-specific conversions matter even for liquids.

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.

Frequently Asked Questions

About 338.18 ml, based on heavy cream having a density of 238g 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 238 (grams per cup), then multiply by 236.588 to get milliliters. For 12 ounces: 12 × 28.3495 = 340.19g, then 340.19 ÷ 238 = 1.43 cups × 236.588 = 338.18 ml.
For the most accurate results, weigh heavy cream 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 heavy cream 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: 338.18 ml ÷ 236.588 = 1.42939 cups, then 1.42939 × 238g/cup = 340.19g, then 340.19g ÷ 28.3495 = 12 ounces. Or use the Milliliters to Ounces converter.
