Mash Calculators
Use these handy javascript calculators to help with your mashing calculations! The formulae are from Ken Schwartz's Calculations for All-Grain Brewers, with the exception of the unit conversion calculations which I got from various sites on the web. These calculators should work as advertised, but use them at your own risk (%$#&* lawyers!). These calculators require the use of Netscape 3.0 or better, or Internet Explorer 3.0 or better.
Also check out Glenn Tinseth's Javascript hop bitterness and water chemistry calculators.

space under your false bottom into account!
