To convert milliliters to US cups, divide by 236.588 (or multiply by 0.00423). For a quick estimate, divide by 240 — this is accurate within 1.4%. The most common reason for this conversion is adapting metric recipes to US cup measures.

For small mL amounts (less than about 60 mL), expressing the result in tablespoons or teaspoons is more practical than fractions of a cup. Tablespoons: mL ÷ 14.787. Teaspoons: mL ÷ 4.929.

Step-by-Step Method

Step 1: Identify the mL value. Step 2: Divide by 236.588 to get US cups. Round to the nearest standard fraction (¼, ⅓, ½, ⅔, ¾, 1). Step 3: For amounts below 60 mL, consider converting to tablespoons (÷ 14.787) instead — the result is easier to measure.

Example: Recipe calls for 350 mL milk. 350 ÷ 236.588 = 1.48 cups. The nearest standard amount is 1½ cups (354 mL) — close enough for cooking. For baking where precision matters more, use a liquid measuring cup with mL markings and measure 350 mL directly.

Worked Examples

Recipe: 100 mL stock
  100 ÷ 236.588 = 0.423 cups
  ≈ slightly under ½ cup  (or use 6.5 tbsp)

Recipe: 240 mL milk
  240 ÷ 236.588 = 1.014 cups
  ≈ 1 cup  (practically exact)

Recipe: 500 mL water
  500 ÷ 236.588 = 2.113 cups
  ≈ 2 cups + 1 tbsp

Recipe: 60 mL oil
  60 ÷ 236.588 = 0.254 cups = ¼ cup

When to Use Tablespoons Instead

For mL values below about 60 mL, cup fractions become inconveniently small. The following tablespoon equivalents are more practical: 15 mL = 1 tbsp, 30 mL = 2 tbsp, 45 mL = 3 tbsp, 60 mL = 4 tbsp (= ¼ cup). When a metric recipe specifies 30 mL of an ingredient, measuring 2 tablespoons is more accurate than trying to fill ⅛ of a cup measure.

Similarly, teaspoon conversions for very small amounts: 5 mL = 1 tsp, 10 mL = 2 tsp, 15 mL = 3 tsp = 1 tbsp, 2.5 mL = ½ tsp. These round values are standard culinary approximations used worldwide.

Quick Tips

✓
Divide by 240 for a quick estimate — within 1.4% of exact.
✓
240 mL ≈ 1 cup — the most useful single anchor for metric-to-US cooking.
✓
For amounts below 60 mL, convert to tablespoons (÷ 15) for easier measurement.
✓
For amounts below 15 mL, convert to teaspoons (÷ 5) for easier measurement.
✓
Measuring in mL with a liquid measuring cup is always more precise than estimating cup fractions.
