A metric recipe calls for 250 mL, but my measuring set is marked in US cups. What should I use?

250 mL is about 1.05669 US cups. It is exactly one metric cup, so substituting a single US cup changes the recipe's volume.

A recipe says 'cup' but gives no country or measuring notes. How should I resolve the ambiguity?

Check its publisher and regional context before converting. This page uses a US cup of 236.5882365 mL, while a metric cup is 250 mL; the difference is large enough to affect a scaled recipe.

Why does converting dry milliliters to cups not tell me how many grams to weigh?

Both milliliters and cups measure volume, while grams measure mass. Flour, sugar, butter, and other ingredients need an ingredient-specific density or recipe reference because packing changes the mass.

Key Formulas

Liter → US Gallon

gal = L × 0.264172

US Gallon → Liter

L = gal × 3.78541

US Cup → Milliliter

mL = cup × 236.588

Milliliter → US Cup

cup = mL × 0.00422675

Formula

US cups = mL ÷ 236.5882365

This page converts milliliters to US customary cups. Divide the metric volume by 236.5882365 when a recipe or label gives milliliters but your measure is marked in US cups. A metric cup is exactly 250 mL, so check the recipe's unit system before converting. This is a volume conversion and does not account for an ingredient's density or mass.
