Grams of Coir in a Quart of Coir?

I have a brick of coir. I am wanting to make only a few shoebox's lets say 3 of them. I am wondering how many grams I should break off from the coir brick for each shoebox assuming a 1:1.5 ratio of spawn to coir substrate.
I guess the easiest way to help with this is... does anyone know how many grams of coir would equal a quart of coir? Dry off the brick quart.
Simply, I am wanting to break off the coir into a bowl on a scale. Weight out the amount needed for 1 shoebox. Put that in my bucket. Repeat two times more and then I'm going to use bods bucket tek for coir substrate (https://www.shroomery.org/forums/showflat.php/Number/24077162) which states you take your coir weight and multiply it by 5 to find your water weight. Do this and let sit in a bucket.

Put it in some kind of quart container and then weigh it?
Unsure i fully understand what your looking for.

Yeah, I guess what I should do is just break some off the brick and kind of try to break it up as best I can to where it kind of just sits in the quart jar like dirt would or something. Then I can weigh it out minus the jar and know how much a quart of coir would weigh in grams.
I can't believe no one else has ever wondered this. I for sure thought search would have brought something up about it. The reason why I am having to do this is some of my jars have finished up faster than others. It's getting cold here. I don't have HVAC heating and air so propane heat is my source of warmth and it only keeps certain areas in my house above 68 degrees.
So I have 6 jars and plan to make 3 shoe boxes out of them but I don't believe that it will take a whole brick of coir. I don't want to make up alot more than i need.

I did it once and I did 40gm dry coir to 1 cup water to 1/2 cup verm.. I think it was about 1 myco qt of bulk sub.. might be a little more or less.. it’s a 1/16 of the standard 650g to 1 gallon water and 2 qts of verm

Just prep a brick and save the excess, in another shoebox, for future use.

bricks i use are 8 quarts per about 650 grams of dry, so if you're doing 3 boxes with 1 quart of spawn you need about 365g dry coir

1 650g brick of coir is around 9 quarts once hydrated.
I say cut it half with a hand saw. Use one half of the coir brick and 1/2 gal water. Shoeboxes take about 1.5 quarts of substrate, so 3x1.5=4.5 which is half your brick. 
The dry weight of a brick is generally 650g so 325g dry coir should be right for 3 shoeboxes.

Thanks for the advice guys. Actually what I ended up doing was using 110grams of dry coir per shoebox then hydrated it. I just used the below teks and divided buy 5 which gave me the amount of coir per shoebox. https://www.shroomery.org/forums/showflat.php/Number/26043706 https://www.shroomery.org/forums/showflat.php/Number/26009662/fpart/1/vc/1/nt/8

There's a nice method in figuring out how much water to add to any amount of coir..
110 grams of coir x 4.75 ---------------------- 522.5 grams of water
If your going to use verm: The same wt. of verm would be the same wt. of water you add.
For an example 1 qt. verm :
100 grams. verm 100 grams water.
This method I been using for a couple of years now and It comes out exactly the same every batch.
If that's too dry you can multiply 110 time 5.0 or If It's to wet you can multiply 110g. by 4.5..
My sweet spot is 4.75. You could find your sweet spot to be different than mine.
I don't like eyeballing to much room for inaccurate measurements.

just prep the whole brick and set the rest aside

There's lots of variation between coir, and water retention. You can nail your exact water ratios, after working with your particular brand of coir. Just because someone uses 4.5 qts of water, doesn't mean you should.

this is true, i followed many coir teks and nothing worked to get my brand of coir to fc right away, it was always too wet. i had to do many trials to figure out what worked for me.

I've been struggling with this also, and was going to start a thread but seen this.
I've been weighting out 110g of dry brick per shoebox. Usually do runs of 5-10 boxes. After hydrating i always find i have twice a much volume of coir that I need for a 1:1.5 volume.
I'm lost as to whether I'm not adding enough coir, as im adding it by hydrated volume, rather than prehydrated weight. My shoeboxes are about 6L and my substrate is usually about 1in deep and if I used all the coir by box would be 1/3rd full!

You’re running them on the thin side, but I’ve done tons of shoeboxes between 1-4” thick without much difference. I finally settled on about 2.5.

Are you keeping the ratio of 1:1.5 by volume or by weight to achieve greater depth?

Neither. I just dump a quart of spawn in and add coir til it’s as deep as I want it.
Unless you’re doing no prep or all in one type stuff don’t get too hung up on exact numbers and ratios. It’ll all work.
