Ever tried making a custard or cake where the recipe demanded grams, but all you had were measuring cups? You’re not alone. Converting cups to grams for milk isn’t just about numbers—it’s about nailing that perfect texture in your dessert. But here’s the kicker: milk’s weight varies slightly depending on its fat content and temperature. Let’s break it down so you never have to guess again.
Unit definitions
What is a cup (cups)?
A cup is a unit of volume used primarily in cooking. In the US, 1 cup equals 240 milliliters. It’s handy for liquids like milk, water, or oil, but can be tricky for dry ingredients due to settling.
- Symbol: c or cups
- Common uses: Measuring liquids, flour, sugar
- Definition: 1 US cup = 240 ml
What is a gram (g)?
A gram is a metric unit of mass. Unlike volume measurements, grams remain consistent regardless of ingredient density. Professional bakers prefer grams for precision.
- Symbol: g
- Common uses: Baking, scientific measurements
- Definition: 1 gram = 0.001 kilograms
Conversion formula
Milk’s density is roughly 1.03 g/ml, slightly heavier than water. Since 1 US cup = 240 ml:
Grams = Cups × 240 ml × 1.03 g/ml ≈ 247 grams
But for simplicity, most recipes round this to 240 grams per cup. If precision matters (like in cheesemaking), use 247 g/cup.
To convert grams back to cups:
Cups = Grams ÷ 240
Example calculations
- 2 cups to grams:
2 cups × 240 g/cup = 480 grams - 500 grams to cups:
500 g ÷ 240 g/cup ≈ 2.08 cups (or 2 cups + 2 teaspoons)

Historical background
The “cup” as a measurement dates back to medieval Europe, where actual drinking cups were used to portion ingredients. It wasnt until Fannie Farmer’s 1896 cookbook that standardized cups became popular in the US. Meanwhile, grams gained traction in the 20th century as scientific baking took off. Fun fact: teh FDA only standardized the US cup to 240 ml in 1975—before that, regional variations caused recipe chaos!
Interesting facts?
- Not all cups are equal: Australian and Canadian cups differ slightly from US measurements.
- Milk vs. water: 1 cup of milk weighs about 3% more than water due to dissolved proteins and fats.
- Fat matters: Whole milk is less dense than skim milk. A cup of skim milk weighs ~245 grams.
- Medieval recipes: Early European recipes used terms like “a noggin of milk” (roughly 1/2 cup).
- FDA quirks: The US allows “1 cup” labels on products to vary by up to 10%—another reason to weigh!
FAQ
1 cup of milk weighs approximately 240 grams, but this can vary slightly depending on milk fat content and temperature.
Yes. Skim milk is slightly denser than whole milk, so 1 cup may weigh 245 grams. Always check your recipe’s requirements.
It’s not ideal, but using a standardized measuring cup and leveling the milk at the rim can give you close results.
Weight measurements (grams) are more precise. A cup of milk can settle differently, but grams ensure consistency every time.
No. A US cup is 240 ml, while a UK cup is 284 ml. This guide uses US cups (240 grams per cup).
