Having Google voice search at the ready is a pretty neat feature of Android phones, but reader Michael Crider shares a tip with us that we didn’t think about before — it also means you have Google’s calculator available via voice activation.
The built-in calculator for Windows 7 is pretty good (and you can use it on Vista as well). If you fancy a more Apple-like experience, iCalcy replicates the built-in iPhone calculator in a standalone application.
Windows/Linux/Mac: SpeedCrunch is an extremely fast and lightweight calculator that supports extended expressions. Instead of pecking away entering your equations line by line, you can enter the whole thing in at once. SpeedCrunch calculates in the background while you’re entering equations, which helps in locating obvious errors as you work. It also supports syntax highlighting, so you can see immediately if you left a parentheses out. It has support for unlimited variables with multi-character names so you can create values for everything from X to SpeedOfAnAfricanSwallow; additionally, a handy ans variable is a quick way to reference the result of the last calculation. SpeedCrunch has a built-in library of mathematical constants, variables, and equations for common calculations of volume and area of 3D and 2D objects respectively. Fortunately with the number of variables available, there’s a snappy search function that is keyboard accessible. SpeedCrunch is freeware with cross-platform support for Windows (available as a portable application), Linux, and Mac. Thanks DevourerKwi!
SpeedCrunchMost people get lazy and just multiply by 1000 (rather than 1024) when converting between kilobytes and megabytes in their heads, but as files get larger, that gets less accurate. BigPond’s customer support site includes a handy ready reckoner that converts between bytes, kilobytes, megabytes and gigabytes. Although not particularly unique, it’s a useful bookmark if you find yourself flummoxed by the mathematics of file size. BigPond Byte Calculator
