> Metric vs. imperial units:
FWIW, Google now has a units conversion feature. Just put "47.38 acres in
hectares" in the search window and it tells you "47.38 acres = 19.1740057
hectares" . Of spacy relevance, you can also do things like "450 pounds
force = 2 001.69973 Newtons", "450 pounds = 204.116567 kilograms".
Actually, it's clever enough to recognize context and will resolve "pounds"
into pounds force or pounds mass depending on the conversion requested. It
isn't clever enough, alas, to avoid generating spurious precision via
gratuitous decimal places, as these examples show.
It also has moderate entertainment value:
3 Parsecs = 2.02472457 × 10^17 cubits
1 * (square league) = 3.43465459 × 10^-10 square light-seconds
> Sorry, I prefer metric with simle decadic structure of units
Me too. Definitions of derived quantities are also easier to figure out:
see the ever-popular flame wars about the proper units of specific impulse.
