The recipes within High Intensity with Kayla Recipe eBooks have been formulated using the Australian Metric System, which uses cups and grams as its primary form of measurement.

A cup is determined by volume, rather than weight.

The water measurement, therefore, equates to:

1/4 cup = 60 mL

1/2 cup = 125 mL

1 cup = 250 mL

If you are using the Imperial System, the conversion will be as shown below:

60mL = 2 fl oz.

125mL = 4fl oz. 

250mL = 8fl oz.
