How much does a medium mushroom weigh in pounds?

A medium mushroom weighs about 0.04 lb (0.63 oz, 18 g). A small one is about 0.02 lb and a large one about 0.06 lb, so the pound total shifts with size. Set the size selector to match the mushrooms you actually have before trusting a per-pound count, since the same weight in pounds maps to a different number of whole mushrooms at each size.

A small white-button mushroom is barely over a third the weight of a large one, so 'eight mushrooms' in a sauce can swing the yield. Pick the right size below to keep risotto, pasta, and stroganoff on target. Sizes here cover white buttons only; portobello caps run much larger and aren't included.

How many mushrooms are in a pound?

About 25 medium mushrooms make up a pound, since a pound is 454 g and a medium mushroom weighs 18 g. With small mushrooms that rises to roughly 45, and with large mushrooms it drops to about 17. Set the size selector to match the mushrooms you have, then read the exact count above.

Got portobello caps? Those weigh 80–200 g whole, well above white button. See our Portobello Mushroom converter.

No scale? The tool below gives a good estimate, but for exact bakes a digital kitchen scale removes the guesswork.

Mushroom varieties and best uses

The conversions above are the same whatever variety you use; the difference is what each is good for. Here is how the common mushroom varieties compare.

Variety	Best for
White Button	Everyday sautéing, soups, and pizza: mild and tender, the standard supermarket mushroom.
Cremini (Baby Bella)	All-purpose cooking: brown-skinned, firmer, meatier white-mushroom variety with deeper flavour. Sold as Cremini, Baby Bella, or Portobellini.
Shiitake	Asian dishes and stocks: woody stems, strong umami; sold fresh or dried.
Oyster	Quick sautés and stir-fries: delicate, fan-shaped caps that cook in minutes.
Chestnut	Roasting and risotto: nutty brown caps, firmer than white button, similar to cremini.
Porcini	Risotto, sauces, and stews: deeply savoury; usually sold dried and rehydrated.

Which should I pick?

For everyday sautéing, pasta, and risotto, Cremini (Baby Bella) gives deeper, meatier flavour than White Button. No Cremini? White Button is the reliable supermarket default. For stocks and stir-fries that want strong umami, reach for Shiitake; for tender quick sautés where you don't want the mushroom to overpower, Oyster.
