Onion (Chopped)
'One medium onion' is cooking's vaguest measurement: it can range from 100g to 300g. For a soup, it might not matter, but in sauces, meatballs, or fillings, excess onion releases water that can ruin the texture. Weighing chopped onion gives you total control over flavor and moisture.

How this conversion works
Milliliters measure volume while grams measure weight. Because Onion (Chopped) has a density of 0.68 g/mL, 10 mL weighs 7 g — not 10 g as it would for water. This converter uses the real density of Onion (Chopped) so every measurement is accurate.
Measurement notes
Values are rounded to the nearest whole gram. Actual weight can vary slightly with compaction, temperature, and brand. For precision baking, a kitchen scale is always more reliable than volume measurements.
