45 grams of bran cereal is equal to how much a metric cup?

You can't directly convert grams to metric cups for cereal, as the density varies between brands and types.

Here's why:

* Different cereal densities: Some cereals are denser than others. For example, puffed rice will be lighter than granola.

* Packing: The way cereal is packed in the box also affects how much fits in a cup.

To get an approximate conversion:

1. Check the package: Look for the nutritional information on the box of bran cereal. It usually provides the serving size in grams and cups.

2. Use a scale: The most accurate way is to weigh out 45 grams of your specific brand of bran cereal using a kitchen scale. Then, measure that amount into a measuring cup to see how many cups it fills.

Remember: This will give you an approximate conversion for your specific brand of bran cereal.
