375 ml to Cups: Convert 375 Milliliters to Cups
Convert 375 ml to cups: 375 milliliters equals about 1.59 US cups. Learn the exact factor and why a half-bottle of wine is this size.
Why 375 ml Comes Up
375 ml is the standard "half bottle" of wine and a common size for specialty spirits and some mixers. The US cup value helps when cooking or mixing from metric bottles.
Three hundred seventy-five milliliters equals about 1.59 US cups. Our ml to cups converter returns it directly; 1.59 cups is the rounded figure.
The 375 ml to Cups Formula
One US cup is 236.59 ml, so divide milliliters by 236.59 to get cups. For 375 ml: 375 / 236.59 = 1.585 cups, rounded to 1.59 cups.
The Exact Calculation
For 375 ml: 375 / 236.59 = 1.59 cups. For 250 ml it is 1.06 cups, and for 750 ml it is 3.17 cups.
To go the other way, multiply cups by 236.59: 1.59 × 236.59 = 375.8 ml, close to 375 ml.
Why a Half-Bottle Is 375 ml
A 375 ml bottle is half of the 750 ml wine standard, about 12.7 US fluid ounces. In cups it is roughly 1.59, just over one and a half cups.
What 1.59 Cups Looks Like
A 375 ml bottle of wine or liqueur pours about 1.59 US cups, just over one and a half cups. It is 0.375 of a liter.
For the liter base, our guide to 1 liter to cups covers the 4.23-cup figure.
When You Need 375 ml in Cups
The conversion matters for cooking with wine and spirits. A recipe calling for a 375 ml half-bottle is about 1.59 cups of liquid.

Common Pitfalls & How to Avoid Them
US vs. Imperial (UK) cups
A US cup is 236.59 mL, but a UK/metric cup is 250 mL and an Imperial cup is ~284 mL. Recipes from different countries are not interchangeable drop-in.
Fluid ounce is volume, not mass
A US fl oz is 29.57 mL of volume. 1 fl oz of water ≈ 29.57 g, but 1 fl oz of honey or oil weighs more. Do not treat fluid ounces as grams.
Teaspoon/tablespoon sizes differ
1 US tbsp = 14.7868 mL; 1 US tsp = 4.92892 mL. Metric measuring spoons are 15 mL and 5 mL — close but not exact; for baking precision use weighed grams.
A unit-conversion reference site has no manufacturer-specific or device calibration parameters, so "layered tuning" does not apply here. The only real error-handling is input validation: the converter rejects non-numeric, empty, or out-of-range entries and shows a clear message, then falls back to exact constants above. No estimated or rounded figures are ever presented as exact.
