In my Support Tools post, I mentioned I am enamored with my ProjectCalc. It does a bunch of stuff beyond a normal calculator, but for me, the winning feature boils down to one key ability, quickly doing calculations with fractions.
Sure, I took basic 5th grade math (a million years ago), and still remember some that cross-multiply and divide crap, but why do it when I can rely on economical technology to do it for me?
I like to save time, instead of scribbling my error filled, unintelligible calculations on scrap cardboard or 2x4s. Plus, it's more accurate than taking off my shoes to count past ten.
I keep it stowed in a drawer of measuring, layout, and marking implements, but like to tuck it in my Nail Apron
when I'm suiting up for project combat operations. Its hinged cover protects it in a pocket, tool bag, or drawer full of tools. Maybe there are some smartphone apps that can do this stuff, but do you want yours to slip out of your hand from atop a ladder? I have a version older (#8515) than the one they are currently selling
; it's probably about 3 years old and going strong on it's original batteries. The rugged construction of this little bulldog has allowed it to survive many projects.
The fraction feature is easy to learn, but takes a few extra keystrokes to accomplish. For example, to divide 7 feet, 3 and 3/8 inches into three equal parts, you tap a few unique buttons (shown here as <BUTTON>):
Therefore: 7ft. 3 3/8 in. ÷ 3 = 2ft. 5 1/8 in. Wham Bam! Done!

In addition to standard calculator functions, it easily converts between decimal and fractional numbers in standard or metric measurements (linear, square, or cubic). It also calculates for paint, concrete, tile, wallpaper and carpet.
The new version takes advantage of a quantum leap forward in project mathematical calculating technologies. Calculated Industries has finally able to harness the power of White and Blue. Gone is the ancient, yellow styling of yesteryear. Of course this upgraded modern technical marvel has been renamed as the Home ProjectCalc Do It Yourself Calculator (#8510). I didn't see any other differences other than additional buttons replacing the dual button function I have to use in order to figure materials.
Calculated Industries has a full line of project / construction calculators with even more features, (like memory storage) but for what I normally do, I'm really happy with the DIY / Homeowner grade calculator. At some point, maybe I'll try out one of the more advanced models, but for about $20 - $30, you can't go wrong with this one.
I've personally used mine for renovation projects, woodworking, and electrical conduit bending calculations. I'm happy to recommend it. It's a tool worth having in your collection.
