How do I get 0.425 of a Cup what does it equal in cups water?

0.425 of a cup is already a measurement in cups. It's a little less than half a cup.

If you need to measure it, you can use a measuring cup with markings for fractions of a cup. You can also estimate it:

* Half a cup is 0.5 cups

* One-quarter cup is 0.25 cups

So, 0.425 cups is a little more than one-quarter cup but less than half a cup.
