Grams per nut -to- Nuts per pound
Some people think in terms of grams per nut, or grams per sample of three nuts (the typical number of nuts in a chestnut burr). Other people are more comfortable thinking in terms of nuts per pound.
The table shown above is a way to switch between grams/nut sample to nuts per pound. For example, the three nut sample in the top photo weighs 122 grams. If that is representative of all nuts in the population than one would expect between 10 and 12 nuts to the pound.
