In order to find size of pistachio (ounce) there are the following stages:
First prepare 142.5 g of pistachio samples.
Make groups of pistachio, there should be five pistachios in each group.
Count the number of the groups. The number of the groups shows pistachio ounce.
For example If there are 21 groups, it’s 20-22, if there are 28, it’s 28-30,…etc
