Support KNF!

This app is handy and I think KNF classes should be mandatory for every person in the world... Even if you know the math, buy this app and support these folks as they are truly spreading an important message!

Note: In the soap calculator KOH is listed as an ingredient but is not explained on the acronyms help page.

Quick reference

Really great for mixing solutions and to check some instructions and storage data when making inputs. Has recipes under the quick help menu. Could use some spelling refinement in those recipes, and some more information on the soap calculator(dilution rates for wetting agent) would be really helpful, but I love the app and use it a couple of times per week.

Easy to use

Super simple if you’re not looking to convert too much. We Run a 5 gallon bucket and a 100 liter bucket. Using this makes it super simple!!
Here’s some other important conversions:

1 us teaspoon: 4.93 ml
1 us tablespoon: 14.78 ml
1 us fluid oz: 29.57 ml
1 us cup: 240 ml
1 US pint: 473.17 ml
1 us quart: 946.35 ml
1 us gallon: 3785.41 ml

(Note: us metrics are different than imperial)

Drake, you’re more than welcome to use that right by the “quick help with solutions” area. It comes in super handy!!
