I would think that could be a tad inaccurate. Doesn't it depend on the malt type and moisture content? I've never seen malt listed in a recipe by measurement. It is always by weight.Bjorn Borg said:2 cups is a pound...
Just make sure the water is at 154 and wait an hour... oh wait, we're not talking mashing?Bjorn Borg said:But if you knew just the mass, you could then find out its volume by placing it in water and measuring the water displaced, then you could simply divide mass into volume and get the density.

Ivan - I would argue that your chemistry teacher didn't sufficiently understand the science involved. Or at least didn't put it into practice.
Maybe. But since he posted this over 6 years ago, I bet he's over it by now.![]()
I checked my scales by weighing a pint of water. It came in at 1 lb 0.6 oz. (A little bit heavy, but I don't know how accurate my one pint measuring jug is.)
This thread is 12 yrs old dude.
Not any more.
But, also, it's the thread I got to when Google searching the question, so it seemed worthwhile to put the tiniest bit of accuracy onto it.![]()
For what it's worth I use a saucepan to measure out everything that when full is roughly 500g. I know there is some variation but for the most part recipes are built around arbitrary whole numbers anyway.. assuming the same ingredient is always going to be about the same density it is perfectly good to build beers using volume and plug it into your progres as a weight. I guess if you get one exactly where you want it you can weigh it out precisely but there is no guarantee that your next batch of grain or hopshis going to have the exact specifications of the last batch anyway.
For liquids (water), "a pint's a pound, the world 'round".
Also, 1 gallon (128 oz) of water = 8lbs. 128/8 = 16.
Are you sure you weren't also weighing the measuring cup?!

Ok, let's be really accurate (and really pedantic). A gallon of water weighs 8.3304 lbs at 20°C (68°F). 20°C is the ASBC (American Society of Brewing Chemists) standard temp for measuring volumes. A gallon of water at 12.9°C (55.2°F) weighs 8.34 lbs (linear interpolation of table at linked reference. If using the ICUMSA or Bettin & Spieweck polynomials the temp for 8.34 is 13.2°C or 55.7°F.)Except that what you posted isn't the tiniest bit accurate.
128 fluid ounces of water isn't the same as 128 ounces in weight. A gallon of water weighs 8.34 lbs, not 8 lbs.
