Not that there probably aren't better examples of the problem you brought up, but for the specific example you gave:
http://www.google.com/search?hl=en&safe=off&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=WtB&q=sqrt(5+acres)&btnG=Search
But also, you can often just ignore the unit conversions until the end of the equation, using the "in" syntax:
http://www.google.com/search?q=sqrt(5+acres+%2B+3+square+meters)+in+inches
or for an extreme example:
http://www.google.com/search?q=(((3.5*g*(in%5E(-3)))*(9.8%20*m*(s%5E(-2)))*sin(0.15%20radians+2%20degrees))/(1000*(Pa*s)))*(((4*m)*(0.1*ft))-(((0.1*m)%5E2)/2))%20in%20knots

If you're looking to export a product from the US, including strong AES encryption will get you hassle regarding ITAR. Yes Virginia, encryption algorithms are considered munitions by the US government. The optimist in me would like to think that in-house crypto solutions are implemented to avoid ITAR issues, and not that someone "knows a better solution."
Very interesting stuff. Santas, and all!

Submission + - New/Old Form of Nanomechanical Computing Proposed (bbc.co.uk)

eldavojohn writes: "The BBC is reporting on a newly proposed type of nanomechanical computer that mimics J. H. Müller & Charles Babbage's work on mechanical computational devices — just on a much smaller level. The paper is published today in the New Journal of Physics and cites three reasons to build a nanocomputer with nanomechanical transistors over bipolar junction transistors or field effect transistors: "(i) mechanical elements are more robust to electromagnetic shocks than current dynamic random access memory (DRAM) based purely on complimentary metal oxide semiconductor (CMOS) technology, (ii) the power dissipated can be orders of magnitude below CMOS and (iii) the operating temperature of such an NMC can be an order of magnitude above that of conventional CMOS." Perhaps the future of computing (the Difference Engine) has been sitting in a museum right under our noses for well over a hundred years?"
