How many grams in a cup of rolled oats before cooking?

There's no single definitive answer to how many grams are in a cup of rolled oats before cooking. This is because:

* Different types of oats: There are various types of rolled oats (old fashioned, quick-cooking, etc.) which have different densities.

* Packing method: How tightly you pack the oats into the cup will affect the weight.

Here's a general range to keep in mind:

* Loosely packed: Around 50-60 grams

* Medium packed: Around 70-80 grams

* Tightly packed: Around 90-100 grams

For most recipes, a "cup" of rolled oats refers to a loosely packed cup.

It's always best to check the specific recipe you're using for guidance. Some recipes will provide a weight instead of a volume measurement, which is more accurate.
