In the first listing of metric units in the U.S., the hectare, are, and
centare (no "i") were listed with their equivalents in acres, square
yards, and square inches, respectively. That was in the Metric Act of
1866 act. See the section "Measures of Surface" at
http://lamar.colostate.edu/~hillger/laws/metric-act-bill.html
page 2. You will also find the stere in the next table.
It's obvious that the are was the "base unit" for area, with hectare and
centare related by factors of 100.

One property seems to be made up of numerous small pieces of land, the

piece will be 1 54 80 (in 3 columns), which as you say is probably 15
480 m2. I did meet a Farmer while I was over there who was originally
from England, he referred to Hectares and Ares which is the first time
I'd heard the use of Ares. I surmised that the origin of the word
Hectare was from Hecto and Are as the Are is one tenth of a hectare.
From brittanica.com <http://brittanica.com>
*are**,* basic unit of area in the metric system
<http://www.britannica.com/EBchecked/topic/378783/metric-system>, equal
to 100 square metres and the equivalent of 0.0247 acre
<http://www.britannica.com/EBchecked/topic/4100/acre>. Its multiple, the
hectare <http://www.britannica.com/EBchecked/topic/259196/hectare>
(equal to 100 ares), is the principal unit of land measurement for most
of the world.

Do you mean it is "mixed base?" The ares are only the residue from an
integer number of hectares? And the centiares (which are square
meters, if that's what they are) are residue from integer ares? (I've
never seen anyone use centiares, so I don't know whether you keep or
drop the "i", centares? It might get confused with a centaur.)
That is pretty shocking usage from the country that claims to have
brought the metric system.
I don't speak French.

I'm looking at buying a piece of property in France. I notice on the
documents that they list the area as Hectares (ha) ares (a) and ca
which I'm thinking are centiare? Anyone on this list have any idea if
this is correct.
On another note, I'm looking for someone to translate a 15 page
document into English, I'm willing to pay for the service.
