Default What is a grain?

Here's a question we sat around the campfire at the GTG and discussed.

We measure arrow weight in grains. What is a grain? What is the standard of measurement that a grain is?

And you can thank huntingson, the threadinator for this one. winky winky.

Well there's your textbook answer.......lol.

In the "old days".....they used actual grains (if I'm not mistaken) to measure weight of smaller objects. Stones to measure heavier objects.....and so on.

Grain
An ancient unit which was originally based on the weight of a grain of wheat. The grain is the smallest unit of weight.

4 grains = 1 carat
24 grains =1 pennyweight
480 grains = 1 troy ounce
5760 grains = 1 troy pound
437.5 grains = 1 ounce
7000 grains = 1 pound
1 grain = 0.0648 grams (0.06479891)
15.432 grains = 1 gram

Josh I don't know. Most everything we use is based on the british measurement systems of old.....but I have no idea what type of grain was used....and I guessed that it was an actual"grain" (based on them using stones, hands, etc...).

Yes, it was based on a grain of wheat or barleycorn. It did become standardized at a point though. Kind of like an "arms length" or a "foot".
