Explanation

Calculation basis: grams per US cup divided by 28.3495 grams per avoirdupois ounce.

Onion Powder uses a recorded reference of 80 grams per US cup in this dataset. Confidence: low. Source basis: and1 ingredient weight chart: 1 cup onion powder = 80 g https://www.and1.com/measurements/cups-in-gram/

Evidence status: source-unverified. The cited AND1 source has not been independently verified. Its current domain context does not establish the original measurement. Whole versus ground form, grind size, settling, and leveling are important because these concentrated ingredients are commonly measured in small volumes.

Questions & answers

Frequently Asked Questions

Is this weight ounces or fluid ounces?

It is weight ounces. This page converts cup volume into ingredient mass, not fluid ounces.

Does grind size change the result for Onion Powder?

Onion Powder keeps one reference basis here, but fine vs coarse grind can change how loosely the spice fills a spoon or cup. Keep the measuring style consistent if you want repeatable results.
