Formula and Step-by-Step

milliliters × 1.03g/ml ÷ 28.3495g/oz = ounces
  1. Start with 500 milliliters of milk
  2. 1 milliliter of milk = 1.03g
  3. 500 × 1.03 = 515.66g
  4. Convert grams to ounces: 515.66 ÷ 28.3495 = 18.19 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 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.

What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Frequently Asked Questions

About 18.19 oz, based on milk having a density of 244g per cup. The exact amount depends on how the ingredient is measured and the specific product.
Multiply the number of milliliters by 1.03 (grams per milliliter for milk), then divide by 28.3495 to convert grams to ounces. For 500 milliliters: 500 × 1.03 = 515.66g, then 515.66 ÷ 28.3495 = 18.19 oz.
For the most accurate results, weigh milk 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 milk 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: 18.19 oz × 28.3495 = 515.66g, then 515.66g ÷ 1.03 = 500 milliliters. Or use the Ounces to Milliliters converter.
