How to Measure 40g of Onion

If you don’t have a kitchen scale, you can estimate 40g of onion by volume. Roughly, one small onion weighs around 70-100 grams, so 40g would be about half of a small onion. Chopped, this equates to roughly 1/3 cup, but for the most accurate results, a digital scale is recommended. This ensures your air fryer recipes turn out perfectly every time.

Common Mistakes When Measuring Onions

One of the most frequent errors is eyeballing measurements, which can lead to inconsistent results. Another is confusing weight (grams) with volume (cups), which doesn’t account for how finely the onion is chopped. For 40g of onion in ounces, always use a scale if possible. This precision is especially important for air fryer cooking, where even heat distribution relies on uniform ingredient sizes.

Storing onions correctly also ensures accurate measurements. Keep them in a cool, dry place to prevent moisture loss, which can affect weight. If you’re prepping ahead, chopped onions can be stored in the fridge for a few days, but weigh them again before use.
