If you’re short on time and just need the answer, here it is: 3/4 cup equals 180 milliliters in U.S. measurements.
This conversion shows up more often than you might expect—especially when you’re cooking from older cookbooks, baking desserts, or following recipes written outside the United States. I’ve run into it myself plenty of times, and knowing this one number saves a lot of second-guessing in the kitchen.
In this guide, I’ll explain where that number comes from, when accuracy really matters, and how to measure 3/4 cup in milliliters without stress.
Where the 180 mL Comes From
In the U.S., one standard cup equals 240 milliliters. Since 3/4 cup is three-quarters of a full cup, the math is straightforward.
240 mL × 0.75 = 180 mL
Once you remember that base number, converting common fractions becomes much easier. This is especially useful if you cook with metric measuring cups or a kitchen scale that displays milliliters.

When This Conversion Matters Most
Not every recipe falls apart if you’re a little off, but there are times when precision really counts.
Baking is the biggest example. Cakes, breads, and pastries rely on balanced liquid ratios. Using too much or too little liquid can change texture, density, and even baking time.
I’ve also noticed this conversion matters when cooking sauces, custards, or homemade dressings. Liquids measured accurately help flavors stay balanced instead of watered down or overly thick.
Using Metric Tools in a U.S. Kitchen
Many U.S. kitchens now include metric measuring cups, digital scales, or multi-unit measuring jugs. If yours shows milliliters, just pour until you reach 180 mL.
If you don’t have metric tools, here’s a quick workaround:
- 1/2 cup = 120 mL
- 1/4 cup = 60 mL
Together, they make 3/4 cup, which equals 180 mL.
I’ve used this split-measure trick many times when traveling or cooking in shared kitchens.
Common Ingredients Measured at 3/4 Cup
You’ll often see 3/4 cup used for:
- Milk or cream in pancake and waffle recipes
- Broth or stock in soups
- Sugar or oil in baking
- Yogurt or buttermilk in marinades
For liquids, the milliliter conversion works cleanly. For dry ingredients, volume still applies, but weight can vary depending on the ingredient.
Quick Conversion Recap
To keep it simple:
- 3/4 cup (U.S.) = 180 mL
That single number covers most everyday cooking and baking needs.
| U.S. Cup Measurement | Milliliters (mL) | Common Kitchen Use |
|---|---|---|
| 1/4 cup | 60 mL | Sauces, dressings |
| 1/2 cup | 120 mL | Milk, water, broth |
| 3/4 cup | 180 mL | Baking, soups, batters |
| 1 cup | 240 mL | General cooking |
