Conversion Formulas

A cup is a non-SI unit used for measuring the volume. Both US and Imperial cups are closely related to fluid ounces and are defined as:

1 US Fluid Ounce = 0.123223 US Cup = 29.5735 milliliters

1 US Cup = 8.11537 US Fluid Ounces = 0.24 liters

1 Imp Fluid Ounce = 0.1 Imp Cup = 28.4131 milliliters

1 Imp Cup = 10 Imp Fluid Ounces = 0.284131 liters

Thus, in order to convert volume given in cups into volume given in ounces, use these formulas:

V_{(US fl oz)}= 8.123223 * V_{(US Cup)}

V_{(Imp fl oz)}= 10 * V_{(Imp Cup)}

Conversion Examples

If You have 2.5 cups (US/Imp) that would be:

V_{(US fl oz)}= 8.11537 * V_{(US Cup)} = 8.11537 * 2.5 = 20.288425 US fl oz = 600 milliliters = 0.6 liters

V_{(Imp fl oz)}= 10 * V_{(Imp Cup)} = 10 * 2.5 = 25 Imp fl oz = 710.3275 milliliters = 0.71032 liters
