I received the 21 December Science magazine from AAAS today. In their 
NetWatch section they cite a conversion site,
   http://www.onlineconversion.com
about which they say:
   In an epic snafu, the controllers of the Mars Climate
   Orbiter failed to convert English units of force into
   metric ones, one of several mistakes that sent NASA's
   $87 million spacecraft into oblivion 2 years ago
   (Science, 8 Ocotber 1999, pl. 207). Don't let your work
   go down in flames. This handy site performs conversions
   faster than St. Paul. From parsecs to hogsheads, the
   calculator handles some 5000 units of length, temperature,
   weight, speed, volume, time, power, and other measures.
   You can change metric to metric, English to metric, and
   for that retro thrill, metric to English.
It does all that and more, apparently. It includes cooking measures, clothing 
sizes, motor oil grades, Roman numerals, etc. I invite you to check it out, 
but don't shoot the messenger (me!).

A couple of asides about the above site. It worked fine on my computer (linux 
OS) when I used Mozilla (v0.9.4) but not when I used Netscape (v4.78). Yes, 
Java and Javascript are enabled on both programs. Also, I inadvertently found 
that there is a www.onlineconversions.com (i.e., plural) that is "under 
construction". That's the wrong site.

I received a copy of NIST's TechBeat (http://www.nist.gov/techbeat) yesterday 
as well and it touts a NIST site for cooking conversions. That site is
   http://ts.nist.gov/ts/htdocs/230/235/household.htm
An anachronistic footnote below this table advises that "For all household 
purposes 1 milliliter may be considered as equal to 1 cubic centimeter." This 
tells me that this table is almost 40 years old (or more) and was devised 
before the liter was redefined in 1964 (abrogating a 1901 definition). During 
that era of non-equality, there was a difference of about 28 parts per 
million between the two.
