What is an Ounce?

Ounces are commonly used in US recipes for cheese, meat, chocolate, and other ingredients sold by weight. Many kitchen scales offer both gram and ounce readings.

Yes, quite a bit. If you spoon the flour into your measuring spoon and level it off, you will get about 114 grams per cup.

This conversion uses the spoon-and-level method, which is the standard most baking references follow.
