e.g., instead of numpy.pi*mg(5,'m')**2 you'd have to wrap pi in mg() with no units as in mg(numpy.pi)*mg(5,'m')**2. val load1: Power Kilowatts (12) // returns Power (12, Kilowatts) or 12 kW val load2: Power Megawatts (0.023) // Power: 0.023 MW val sum load1 + load2 // Power: 35 kW - unit on left side is preserved sum should be (Kilowatts (35)) sum should be (Megawatts (0. If you want data size conversions in multiples of 1024, use kibibytes, mebibytes, gibibytes, etc - see en./wiki/Kibibyte. Click on a file to display its revision history and to get a chance to display diffs between revisions. It also has the downside that you can't freely switch between the objects created my mg() and the usual numeric types. pkgsrc/math/ Click on a directory to enter that directory. Now, the conversion of 80 m to kilometers is simply the use of a metric prefix, as we saw in the preceding section, so we can get the same answer just as easily by noting that. This module still has a semi-serious bug which causes it to give very misleading output if you try to assign an invalid unit to an existing variable. You can use this method to convert between any type of unit. It works like this: > from magnitude import mg

There are a few options available (one of the curses of a language that's popular among CS folks), but I think the magnitude module is the cleanest looking. high precision scientific calculator with full support for physical units. It features a syntax-highlighted scrollable display and is designed to be fully used via keyboard. I haven't used the units library enough to vouch for its stability, but R libraries are typically very stable and well tested. SpeedCrunch is a fast, high-precision scientific calculator. A simple yet powerful calculator that includes standard, scientific, and programmer modes, as well as a unit converter.

However, if you try an operation that mixes units of the same dimensions, it just puts the result in one of those units: > 1*m + 1*mm By SpeedCrunch Free Download Now Developer's Description By SpeedCrunch Scrollable display. If you try an operation that mixes dimensions, it throws an error: > 1*m + sigma It looks something like this: > library('units') I would suggest finding a package for doing this in your programming language of choice, since you're going to be using that to check/automate your engineering calculations anyways.
