Carat is the unit for measuring the weight of diamonds and other precious gems.

It is the weight of a carob bean of the Ceratonia Siliqua tree.

Carob beans are amazingly alike and weigh 0.2 grams each!

One hundred and forty two Carob beans or carats constitute an Ounce.

The carat is further divided into one hundred points.

So each point will be equal to weight to three crumbs of bread!
