Milk Grams to Cups Converter
100g of whole milk is about 0.41 US cups, using our reference of 244g per cup.
Enter your milk weight below to convert another amount. This page uses fluid whole milk, not milk powder, condensed milk or a universal reference for every milk product.
Reference: The USDA's Nutritive Value of Foods, page 20 lists fluid whole milk, with no milk solids added and 3.3% fat, at 244g per cup. We adopt that weight for this site's US Customary setting. The publication was revised in 2002; this is a published reference, not a new measurement of your milk.

Are grams and milliliters the same for milk?
No. Grams measure weight; milliliters measure volume. Our reference assigns 244g of whole milk to the site's 236.588mL US Customary cup, so those numbers are not interchangeable.
If a recipe gives milliliters, use the volume markings on a measuring jug. If it gives grams, weigh the milk or use an ingredient-specific conversion. Do not assume that 250g means 250mL.
You also need the right cup size. A cup marked 250mL is different from this chart's US Customary cup. Our cup-size guide explains the supported settings.
How to measure milk
With a kitchen scale:
- Put an empty bowl or jug on the scale.
- Press tare or zero so the container's weight is excluded.
- Pour in the milk until the display reaches the recipe's gram amount.
Add it slowly near the target. Weighing into a separate container makes an accidental excess easier to remove before the milk joins other ingredients.
With a liquid measuring cup, place it on a level surface and read the mark at eye level. Betty Crocker's measuring guide recommends this approach for liquid ingredients. Measure the liquid rather than a layer of foam above it.
How the milk conversion works
For this page's US Customary reference:
Cups of whole milk = grams ÷ 244
For example, 250 ÷ 244 = about 1.02 cups. Keep the full value while calculating and round only the final display.
For the reverse calculation, multiply cups by 244. Under the same reference, ½ cup is 122g and ¼ cup is 61g. Switch the calculator's direction above, or use the cups-to-grams converter with whole milk selected.
Can I use the result for other types of milk?
The selected reference is whole milk. Do not assume it applies unchanged to condensed milk, evaporated milk, milk powder, cream or plant-based drinks. If your recipe or product gives its own gram equivalent, use that reference.
The source also lists reduced-fat and low-fat milk, but this calculator does not automatically switch between products. Check what is selected before relying on the result. Similar cup weights do not establish that different milk products are interchangeable in a recipe.
What changes with a metric cup?
Choose Metric in the calculator for a 250mL cup. Scaling our whole-milk baseline by volume gives about 257.8g per metric cup. This is a calculated estimate, not a separate USDA metric-cup measurement.
The table above stays on the US Customary setting. Read our methodology for the adjustment and rounding rules, or visit the grams-per-cup chart for the full ingredient references.
