How many Ounces are in a Cup

To answer the question how many ounces are in a cup? we must take into account that there are both, different units of fluid ounces, as well as different units of cups to measure volumes.

The US customary fluid ounce, the US food labelling fluid ounce and the Imperial fluid ounce are the different ounces under discussion.

In the UK and Canada, the imperial fluid ounce is used.

On the other hand, “cups” can mean US customary cups, US legal cups, metric cups, imperial cups as well as Canadian cups.

One US (liquid) gallon is defined as 3785.411784 ml, and one imperial gallon equals 4546.09 ml.

The majority of the units ounce and cup are derived from the gallon and defined as follows:

1 US customary fluid ounce = 1/128 US gallons
1 US food labelling fluid ounce = 30 milliliters
1 Imperial fluid ounce = 1/160 imperial gallons

1 US customary cup = 1/16 US gallons
1 US legal cup = 240 milliliters
1 Metric cup = 250 milliliters
1 Imperial cup = 1/16 imperial gallons
1 Canadian cup = 1/20 imperial gallons

Both Canadian cups and imperial cups are fractions of the imperial gallon defined as 4546.09 ml.

As the former unit is 20% less than the latter make sure to get your cup unit right.
