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 exactlyFrequently 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.
