A free, public domain, hopefully useful program called DIMCALC is
available. It is a new kind of calculator and units converter which
"understands" physically dimensioned quantities in a way unlike any
other software I know of. It recognizes and manipulates lengths,
velocities, temperatures, surface tensions, etc., and any combination
of such, in addition to ordinary numbers. It allows one, e.g., to
add velocities such as "1 meter per second" and "1 furlong/fortnight"
and then multiply the sum by a time "1 week" to get a distance. The
interface has a choice of functions, memory cells for storage, and
the ability to display inputs and results in terms of an infinite
number of built-in and user-defined units.
It runs under Windows 3.1, comes with extensive help files of
documentation, and user-extendable unit-definition files.
The file dimcalc1.zip (approx 70KB) contains all the software, help,
and data files. Also get the VBRUN300.DLL subroutine file if you do
not have that already. Both are available by anonymous FTP from
FTP.CTR.COLUMBIA.EDU in the directory USERS/HART/
