Medium 5.75 ounces0.16kg
Large 10 ounces 0.29kg

According to the hand size

You can estimate the size of the potato by holding it in your hand and then determine the weight according to the size. For having a rough idea, we can say that a large potato is nearly the size of an avocado and will fit in the palm of your hands without curling your fingers around it. A medium-sized potato will fit 3/4th of your hands, and if you measure from the wrist end of your palm, you will get free space near your fingers. A small-sized potato will only fit your palm and would not touch the fingers of your hand.

According to the pound system

You can also calculate the size of the potato in pounds. To determine the size of potatoes for a 10-pound sack, the estimated weight can be represented in pounds or grams. Such as,

          Potato size
                        Weight of potatoes 
In pounds (lb)In grams (g)
Small 0.21 lb0.10 g
Medium 0.36 lb162.73 g
Large 0.63 lb285.83 g

You can easily estimate the size of the potato with any of the mentioned methods, but sometimes the recipe calls to add medium-sized potato, but you only have two large potatoes. What you can do is estimate the weight by holding the potatoes in your hands. Then cut a half or a little more than that of the potato. It will make your cooking more manageable, and many recipes use potato size as a reference so that it would not be that much of a trouble.

Similarly, in two cups, the amount in grams increases to 450g which is 15.9 oz, which means three medium potatoes or one large and one medium potato.
