Calculatormatik is a tiny (196KB) portable calculator which provides 100+ conversion options and tools.
The interface is, well, a little basic - just a resizable box with a list of the various calculators. These are arranged in alphabetical order, too, rather than grouped by types, and the names don't always make it entirely clear what they do. But if you spend a while poking around, you'll find some useful tools.
Take the "Area Calculator", for instance. Sounds simple, but it doesn't just let you calculate the area of, say, a circle, or square. You can also select an ellipse, a kite, a triangle, trapezoid and more. And there are options to calculate the surface area of cones, cylinders, spheres and a torus, amongst others.
The "Weight Converter" is similarly varied, with support for converting grams and milligrams, pounds and ounces, grains, stones, Newtons, carats and more.
There are assorted mathematical tools: a geometric progression calculator, along with quadratic and simultaneous equation solvers. Software-related options include a "Byte Converter" (convert between bits, bytes, kilobytes, megabytes and so on), a "Base64 to String" converter and "MD5 Hash" calculator. And specialist tools cover topics like "LED Resistance" and "Bass Fishing Boat Speed".
And if you're not the mathematical type, don't worry, there are plenty of more general tools available. Enter your birth date in the Birthday Calculator to see your age in months, weeks, days, hours and minutes, for instance. Dieters may appreciate the Body Mass Index and Basal Metabolic Rate calculators. There are practical calculators to help you figure out mortgage and lease repayments, compound interest and fuel consumption. And you even get tools which really aren't calculators at all, though they're still useful: a simple stopwatch, say, and a random password generator.
