So 100g of onion powder is about 0.83 cups, 200g is about 1.67 cups, 250g is about 2.08 cups, and 300g is about 2.5 cups.

How to measure onion powder accurately
For the most reliable baking results, weigh onion powder on a kitchen scale rather than scooping by volume. One US cup of onion powder weighs about 120 grams (4.23 oz), but the exact figure changes with how tightly it's packed and the brand. Scooping straight from the bag compacts onion powder and can leave you 15 to 20% over, so spoon it into the cup and level it off for the closest match to the figures above. Use the tables for quick reference, or the converter for any custom amount in cups, grams, ounces or tablespoons.
Tip: Onion powder dissolves and distributes evenly, making it ideal for dry rubs and dressings where chopped onion would be intrusive.
