The base
unit of length in the metric system is the meter. The
base
unit of area is the are. A hectare is 100 ares (by
definition). The
base units of volume are the liter (well known and
originally
intended for liquids (think "quart")), and the
rarely used stere
(originally intended for solids (think "cubic
yard")).
A liter was defined as both a kilo of water and as 10 cm *
10 cm * 10
cm. (1000 cubic centimeters)
A stere was defined as 1 m * 1 m * 1 m ( a cubic meter.
The are is apparently defined as 10 m * 10 m (100 square
meters). A
somewhat odd choice. Not exactly intuitive.
Dear Leonard,
Thanks for expanding my
understanding of the world.
Lifelong metric user here, and I had
never _heard_ of ares and steres before this discussion.
Perhaps that is because they never made the jump to
international use when the metric system was formalised in
the late 1800's in the way that tonnes, hectares, and
litres have.
I had
always assumed that the "hecto-" prefix somehow
had to do with the "100" metres on each side of a
square.
Cheers,KB.

Here's something interesting;
Over the years I've used a number of Metric Conversion calculators but none has 'ares', only 'hectares'.
However, my 'flip phone', which came along much later, does have 'ares'!
