Officially, a US Cup is 240ml (or 8.45 imperial fluid ounces.) This is slightly different from an Australian, Canadian and South African Cup which is 250ml.
Check it out: The metric systemâpreferred in most places worldwideâdeclares a cup to be 250 milliliters (about 8.45 fluid ounces), though the accepted standard cup in American measurement is a solid 8 fluid ounces. American cup (used for nutritional information) actually tops off at 8.12 ounces (240 milliliters). To further complicate things, according to the Japanese, a cup is staunchly 200 milliliters (6.76 ounces), but the instructions that came with your Chemex brewer insist it's 5 ounces (about 148 milliliters).
