How to convert 140 grams to a cup- bake

It depends on what you are measuring. Grams are a unit of mass while cups are units of volume. To convert between the two you need to know the density of what you are measuring. For example, there are approximately 200g of sugar in a cup and 125g of all-purpose flour in a cup. What are you trying to measure?

I always google such conversions. It equals 4.98 (I would call that 5) ounces.
