Grams to grains conversion?
« on: April 11, 2012, 02:26:50 am »
I don't have a grain scale yet.  Any one know how to do this?  I'm weighing my arrows ont he kitchen scale and wondering how I fall?  I have two new fishing arrows almost finished and they are 36 and 38 grams.

1gram = 15.4323584 grains so your 38 gram = 586.5
Hope this helps.

So then my arrows aren't unusualy light for normal purposes if 500 - 600 grains is typical for primitive hunting arrows.  My issue for fishign is the buyancy only?

What weights do you guys like for turkey and pigs?

I use the same arrows for everything(although I do not bow fish), hunting, target and 3D.

Most commercial fishing arrow shafts weigh 700-1000grains or so.  I've never weighed mine but I had a friend who deer hunted with them and he said his were about 800gr finished out.  The additional weight helps them go deeper in the water, but from experience I can tell you that if you're shooting more than a foot deep into the water it is VERY hard to aim because of light refraction.  I've shot a few carp with cedar arrows and they worked fine though the carp broke them pretty easily.  I used to drill a hole in the arrow near the tip and one near the nock.  I'd thread the line from the "reel" through the nock hole, tie it off with a lot of  free line and then wind that line around the arrow several times before tying it at the point end.  Then, when the carp broke the arrow, at least I got to pull them in.  Now I use glass arrows, even with my primitive bows, though it isn't very primitive.

Like Pat I use the same arrows for everything. I don't bow fish either. My arrows average 650 grains out of my 47-53# bows.

I'm not shooting my nice boo or cane arows in the water on purpose, I'm using heavy Yellow Jackets. If you Google grains to grams, there are a lot of different conversion sites you can save.

You can actually google any kind of measure conversion and google will directly give you the result . Like "550 grains in gram", similar wordings will also works. I use this often as I am metrically minded  :D and virtually everything I get to read about bow making is using the funny inches, feet and pound measures.

What measure do you guys use when things get small, by the way? like 1/25 inch?

We go to decimals.  My micrometer reads in 1/1,000ths, so 1/25th would read .040" on it.

  I don't even weight my arrows anymore. The bucks can't tell the difference in 20,30,40, grains and all my set ups are 10 to 15 yards. I use the same set up (arrows,trade points) for everything.
  Most of my arrows are dog wood never weighted any in the last 15 years but I'd say there 500 to 600 grains.
