    I saw a couple nice calculators recently on brewheads.com

    New Volume Calculator - This calculator will tells what volume your wort needs to be to change it to a specific target gravity.

    New SG Calculator This calculator tells what the gravity of the wort will be when the volume is changed from the current amount to a new one.

    These are usefull if you need to tweak the volume or fermentals of you wort or need to add water to the fermentation bucket.

    Might be nice to add them here also.

    Re: Calculator request

    Just so we are clear, this would apply to extract brewing?

    Re: Calculator request

    My thoughts were that it would be useful for AG or extract brewing. I was reading this article about hitting your OG. http://www.hoptomology.com/2012/02/14/h ... l-gravity/. Where he missed is OG based on a given volume after the mash. From the calculations, he could determine if he needs to boil longer to raise the OG or add more fermentable materials.

    That lead me into a discussion about taking a gravity reading after you cooled your wort and before you put in fermenter bucket. If I wanted a 5 gal batch, and I started with 6 gal boil, my boil off might be 2 gal. I will get a better gravity reading from the wort before adding 1 gal of water back. If my BG ended up being on the low side, I might not neet to add a full gal So if I take the reading and then caculate what volume I need to add to hit my OG I could add that to fermenter bucket and do not need to take another reading because I would be at my OG from the given calculation. specific gravity x volume = gravity units

    After reading the article, I found the couple useful calculators related to adjusting your volume based on your starting OG and your target OG and your current volume. http://www.brewheads.com/newvolume.php


    And then another calculator will tell you what your OG for a target volume based on gravity reading and current volume and Your target volume. http://www.brewheads.com/newsg.php

    Both I guess come from the same formula. specific gravity x volume = gravity units

    Hope this makes some sense about what I'm trying to say. I'm just getting into home brewing so I may be off target.

    Re: Calculator request

    I agree with Silverbullet. I have run into the same situation with extract and partial mash brewing and would love to have these calculators available on BF.

    Hey guys,
    Yeah I can see using this for AG too, when I want to estimate my OG based on my pre-boil gravity... nice ideas. This will go out in the next release!
