Millilitres to Cups Converter

Understanding Millilitres to Cups

Millilitres are a metric volume measurement, and one US cup equals 236.588 millilitres. This is a straightforward volume-to-volume conversion, unlike conversions involving weight measurements. However, remember that US cups differ from UK cups (250ml) and metric cups (250ml) — a difference of about 6% that can affect recipe outcomes.

When to Use Millilitres to Cups

Converting millilitres to cups is necessary when you have a recipe in metric measurements (common in Europe, Australia, and other countries) but prefer working with cup measurements, or when your measuring tools are marked in different units. This is one of the most common conversions for international cooking.

Practical Tips

This conversion is particularly useful when following European or Australian recipes that use millilitres, or when you have a measuring jug marked in millilitres but need cup measurements. Most measuring jugs show both units, making visual conversion easy. For small amounts, remember that 60ml ≈ ¼ cup and 120ml ≈ ½ cup.

Quick Tips

• 236.588ml equals 1 US cup (often rounded to 237ml)
• 250ml equals 1 UK or metric cup, which is larger than a US cup
• This conversion is accurate for all liquids since both measure volume
• Common conversions: 100ml ≈ ⅓ cup, 250ml ≈ 1 cup (UK), 500ml ≈ 2 cups

Common Mistakes to Avoid

The most common error is using 250ml = 1 cup when the recipe uses US cups (which are 236.588ml). This 6% difference compounds in larger recipes. Another mistake is trying to convert millilitres to cups for dry ingredients and expecting the same accuracy as weight measurements — volume measurements for dry ingredients are inherently less precise.

When Precision Matters

For most cooking, approximate conversions (240ml = 1 cup) work fine. Precision matters for cocktails, candy making, and recipes where liquid ratios are critical. When baking, consider that the original recipe was likely tested with specific measurements — if it calls for 300ml, measuring exactly 300ml will give better results than converting to 1¼ cups.
