How many cups is 5 fl oz?

5 US fluid ounces is about 0.62 US cups, since one US cup is 8 fluid ounces (147.87 ml total). It is not a round number of cups, so for baking it is usually easier to measure 5 fl oz directly, or in millilitres: 147.87 ml (US) or 142.07 ml (Imperial).

Multiply by the size of one fluid ounce. US: 5 × 29.5735 = 147.87 ml. Imperial: 5 × 28.4131 = 142.07 ml. To go from millilitres back to fluid ounces, divide by the same factor.
