Geeky fun with pistachios

So this evening I decided to have some pistachio nuts. We got a 1.5lb bag of them so I measured out one full cup (8oz fluid volume) of them. I weighed the measuring cup first and then pressed the tare weight function on the scale to zero it out and proceeded to fill with pistachios.

Total weight of one cup of pistachios in my case was 3.5 ounces.

I ate the pistachios and then saved the empty shells and weighed those. It comes out to 1.5 ounces.That leaves 2.5 ounces of pistachio.

So doing the math, 1.5 divided by 3.5 yields 0.42857142857142857142857142857143 (Dig the repeating sequence there!) which I rounded up to 0.43 or 43%, which is also the last two digits of the decimal portion. 

So 43% of the weight of pistachios is their inedible shell. The bag we got was 24oz total which yields 10.3oz of shells, 13.7oz of edible meats.

And here is the other thing. The pistachios are also sold in a 10oz. bag. In that case the yield of pistachio meats is only 5.7oz!
