grains of water to CC?

[jr81452]

does anyone have a direct conversion from grains of water to cubic centimeters? i am trying to find the difference in volume of my 308 brass between fire formed and FL sized. i have the difference in grains of water but i can't seem to locate a conversion formula.
thanks

One cubic centimeter of water = 1 milliliter of water = 1 gram

1 gram is approximately 15.432 grains

(Ignoring water's changing density with temperature . . . )

scratching my head here...

but, if I remember correctly....

one Liter (1,000 cc) of water at standard temp. = 1KG

1 KG = 2.205 lbs

1 lbs = 7,000 grains

do some math on your calculator and away you go....

only thing to remember is that the mass of the water that fills your case will vary slightly with temp.

Not sure if this helps -

1 ounce [US, liquid] = 29.573 529 563 cubic centimeter

There is no real reason to convert from grains of water to cc or mL. Reason is that case measurement volume for ballistic programs is measured in grains of water, as is black powder volume. It grew up with the industry.

ugh i was hoping someone would come along and say 1gr water= xCC. to tired to go the long way round. it will have to wait until tomorrow. thanks for the info flinch it will save me some time when exbal comes in this week. but for now i'm just looking for a relative difference in case capacity for some load calcs.

Ok, 1 grain weight of water = .065 CC's.

Knowing that, how does it help with any reloading data?

Google has a nice feature. You can type stuff in the search bar like ".223 in to mm" and it will do the math at the top of the search results. You can also do weight, currency, and a lot of other stuff.

You can also use this site for a lot of stuff.
