In many Metric recipes, 1 cup is 250 mL (common in Canada, the UK, Australia, and New Zealand). In the US it's about 236.6 mL; that's why results can differ.
How Do I Convert 1 1/2 Cups to mL?
Quick explanation
Use this page when a recipe calls for 1 1/2 cups and you want one clear mL total for scaling. The direct answer is 375 mL in Metric mode or 354.9 mL in US mode. This amount shows up when doubling smaller recipes, making smoothies, or scaling soups and sauces without jumping all the way to 2 cups in one step during prep at home.

Calculation steps
How to convert 1 1/2 cups to mL exactly
mL = cups × cup-size-in-mL
For this page, cups = 1.5. Use 250 mL for Metric cup and 236.588 mL for US cup.
Practical kitchen rounding
1 1/2 cups ~ 375 mL (Metric) or 355 mL (US)
Nearest 1 mL is usually sufficient for daily cooking; stay on one cup standard through the recipe.
Worked example (this page)
Input: 1.5
Metric: 1.5 x 250 = 375 mL; US: 1.5 x 236.588 = 354.88 mL.
Practical: use 375 mL (Metric) or 355 mL (US).
About these units
Why cup values differ
Cup values vary by region, so 1 1/2 cups is not one universal mL result. Once recipes move past 1 cup, the difference between standards starts becoming easier to notice in both yield and texture.
- Metric cup = 250 mL (common in metric-standard recipe sources).
- US cup = 236.588 mL (common in US recipe sources).
- At 1 1/2 cups, the gap is about 20.1 mL between standards.
Millilitre (mL)
mL is a metric unit useful for precise measuring jugs and consistent scaling. For an amount like 1 1/2 cups, switching to mL usually makes scaling feel simpler and more repeatable.
- 1000 mL = 1 liter.
- mL outputs reduce ambiguity when sharing recipes across regions.
- 375 mL is a common, easy-to-pour metric checkpoint.
Tips
When baking matters, weigh ingredients; volume can vary with packing and humidity.
If you're using cup fractions (1/3, 1/4), check the quick-reference table for common values.
