Any one care to say if my math is right?

Mash ratio
1.33 qt/lb
1.25 L/lb
2.75 L/kg

Have I got it right? (I know it's variable, it the convertion I'm trying to figure)

What about this?
Absorbtion Rate
0.1 g / lb
0.38 l/lbs
0.83 l/kg

Thanks

Guess not. Don't blame you, have a homebrew instead.

Gotta run, my rabbit smells like it's done.

Thanks, straight conversions are easy; it's the ratios and volume/weight thing that I find tricky

Kettle loss 5.0L

I find all math tricky.

You should have seen me trying to figure out how much brewing water I needed before I had promash.

Right assuming US liquid gallons and quarts, but not for Imperial, German or Ancient Hebrew quarts.

Thanks, yes it's US to metric.
All the best (or most) of the recipes seem to come from over the pond.
