As promised, I have added another tool to my "Bread Baker's Toolbox" for anyone to use. I call this one "The Custom Batch Formula Tool". You use this one when you have a bread formula with the ingredient quantities already specified by weight and you want to create a custom batch size. The software does the math, calculating the Baker's Percentages and displaying the results for your custom batch in both grams and ounces (US). I chose these units because they are the most common used in bread formulas by the home baker. Some large batch formulas will use pound (lbs.) and fractions of pounds. This is simple enough to solve; If you want a custom batch for 5  pounds so you can have 5 one pound loaves, just multiply 5 x 16 to determine total ounces for your custom batch. Anyway, I've put this tool through the paces...its very fast and accurate. Sometimes the final dough weight will equal 699 ounces when you specified 700...this is because each ingredient is rounded to 1/100 of and ounce or 1/100 of a gram. (you don't want to work with numbers that look like this: 234.34453040304004). Give it a try and let me know if you have any questions or suggestions for improvements. Trust me, I can take the critical comments. As a software developer, I know that the product is never good enough for everybody and I can live with that....I just do my best:) Go to breadmagic.com and follow the link. You can now choose between the Volume Conversion Formula  Tool and this new Custom Batch Formula Tool.
