Conversion Formula

mL = cups × 236.588
1 US cup = 236.588 mL (exactly)
Metric cup (AU, CA) = 250 mL

Fractional cups (US / metric):
  ⅛ cup = 29.6 mL  / 31.3 mL
  ¼ cup = 59.1 mL  / 62.5 mL
  ⅓ cup = 78.9 mL  / 83.3 mL
  ½ cup = 118.3 mL / 125.0 mL
  ¾ cup = 177.4 mL / 187.5 mL
  1 cup = 236.6 mL / 250.0 mL

Common recipe liquids (1 cup US):
  Water  = 237 mL ≈ 237 g
  Milk   ≈ 240 mL ≈ 245 g
  Oil    ≈ 218 g (lower density)

Note: 4 US cups = 946 mL (not 1 liter)
      4 metric cups = 1,000 mL exactly

Frequently Asked Questions

How many mL is ½ cup?

½ cup equals approximately 118.3 mL. This is a very common measurement in recipes. Note: an Australian or metric ½ cup is 125 mL.

Is a US cup the same as a metric cup?

No. A US cup is 236.588 mL. A metric cup (used in Australia, Canada, and New Zealand) is exactly 250 mL — about 5.5% larger. When following international recipes, check which cup size is used.

How many mL is ¼ cup?

¼ cup equals approximately 59.1 mL (or 60 mL rounded). This is also equal to 4 tablespoons or 12 teaspoons.

How many mL is ¾ cup?

¾ × 236.588 = 177.4 mL — often rounded to 177 or 180 mL in recipes. An Australian ¾ cup is 187.5 mL.

Why are 4 cups not exactly 1 liter?

4 US cups = 946.4 mL, not 1,000 mL. The metric cup (250 mL, used in Australia and Canada) was specifically designed so that 4 cups = exactly 1 liter. The US cup was not designed with this metric alignment.
