This is my favorite one...
Convert is an easy to use unit conversion program that will convert the most
popular units of distance, temperature, volume, time, speed, mass, power,
density, pressure, energy and many others, including the ability to create
custom conversions!

Not what you're thinking, but MathCad (_not_ MatLab!) lets you dimension
your variables, and will track units. I've found this very handy doing
electromechanical work, where the motor constant that converts current
to torque also converts radians/sec to volts, and for making sure that
my equations make sense (it barfs if you try to add variables who's
dimensions don't match). Furthermore, it treats dimensioning as any
other variable, so you can define furlongs, cubits, grains, "tim-units",
whatever and use them as a regular dimension.

Very handy at ferreting out bogus equations too.
I ran into one with a Seiko printer for caclulating burn energy.
Their formula works, and looks good at first, but when you get to about the
500'th pixel line, it starts giving you negative burn energy.
It does force you to think about things properly.

I remember the time the old retired-Navy lab tech told me that he had to
adjust the pot "just an RCH" to get the circuit to work, and the
newly-hired, red-headed female programmer aksed me what he meant.

Why, "Red Curly Hair", of course.

No, I think that is quite a bit too coarse. My unimpeachable sources
give the approximate measure as 0.0025" (Is that a Starrett in your

That would be a National Fine RCH I believe. ;-)

I believe you are confused by the difference between the Swedish standard
and the Spanish standard.

The most regressive engineers in the world are the thermal guys. They
still work in stuff like BTU-sqfoot/hour/inch/degreeF and nonsense
like that. That junk is a real nuisance to convert into sensible
units. The thermal-pad boys often mix units on a single data sheet
(and lie, to boot.)
Listen up: use watts, meters, Kelvins, Joules, and seconds! I wish the
calorie had never been invented.
grrrrr.

I agree. How much more sensible it would be to be on a 66 watt diet
instead of, what is that anyway, about 2000 Calories?

Yes, that's why I spelled it Calories instead of calories, but it's
not 66 watts.
Since 1 calorie = 4.186 joules, 2000 calories would be equal to 8372
joules, and 2000 kilocalories would be equal to 8,372,000 joules.
Since 1 joule per second is one watt and there are 86,400 seconds in a
day, 8372000 joules/86400 seconds ~ 96.9 watts.
So, if we're consuming 2000 Calories a day, that's about 100 watts.
