How many grams are in 1 cup of quinoa?

One cup of uncooked quinoa weighs about 170 grams. Quinoa seeds are small and dense, so they pack more tightly into a cup than a light grain like oats.

Is this conversion for cooked or uncooked quinoa?

This tool converts uncooked (dry) quinoa. Cooked quinoa absorbs water and roughly triples in volume, so a cup of cooked quinoa weighs more but contains far less dry quinoa by weight.

Does the color of quinoa change its weight per cup?

Not meaningfully. White, red, and black quinoa have very similar seed density, so the 170 g per cup figure applies closely across common varieties.

Why does my quinoa weight not match the package label?

Brands and rinsing methods can shift bulk density slightly, so package-listed weights can differ from this chart by a few grams per cup. For best results, weigh against the specific brand you are using when a recipe is weight-sensitive.

Is it better to measure quinoa by weight or by cups?

By weight. Scooping technique changes how much quinoa fits in a cup, while a gram measurement stays consistent every time, which matters most when scaling a recipe up or down.

How many grams is 1/3 cup of quinoa?

One-third cup of uncooked quinoa is about 57 grams, based on the 170 g per cup density used throughout this tool.
