Converting from quarts to cups is pretty straightforward. For both US and UK systems the conversion is 1 quart = 4 cups, so the formula becomes: X * 4 cups.
For example, if you wanted to convert from 5.23 quarts to cups the formula would look like:
5.23 quarts * 4 = 20.92 cups
However, although US and UK systems use the same number of cups it is still technically a different volume because 1 US cup = 236.59 mL and 1 UK cup = 284.13 mL.
