I agree with and have added to seglea's comment on the usage of 'hectares'.

I have observed in several Wikipedia entries that Bobblewik has changed measurements in hectares to square metres, and in some instances to square kilometres, despite the general practice of describing such land areas in hectares. (Notably, equivalent measurements in acres have not been changed to square feet.) This is objectionable. It seems best to use metric measures in Wikipedia in the way that people who use the metric system use them; the point is to communicate clearly, after all.

In my experience (Australia) hectares are used for land measurement except for small (e.g. urban residential) properties when square metres are used as they are for describing floor areas of buildings. Square kilometres are used only to describe vast outback properties. However, many people are still more familiar with acres and most historical documents describe land areas using acres.

It would be more useful to work at ensuring that all land areas in entries are described in both hectares and acres, rather than conducting purges of the rather useful hectare.

Given that some people use acres, and some hectares, it might be an idea to state the relative areas of each in relation to each other. JTD 07:48 Jan 11, 2003 (UTC)

The word "hectare" is a contraction of "hectametre squared".

Rather, I think, it is a contraction of hecto ("hundred") and are, just as hectolitre from hecto and litre.

Will double check, but I think I was right with the first juncture....

it's "hect + are" -- Tarquin 09:21 14 Jun 2003 (UTC)

it would also be helpful to have a conversion to square feet (107,639 sf/hectare) -- n8dunn@lycos.com

I have reinstated the information about the way in which hectares are used world wide. I know that user:Bobblewik objects to Wikipedia using them (though s/he seems to be in a minority of one on this), but I consider the information that everyone else does use them to be valid encyclopaedic material, and I request that this should not be deleted again without a consensus on this page. seglea 06:27, 28 August 2005 (UTC)

[edit] Definition

The definition given is 10 000 m². That the hectare is 100 ares is mentioned in the conversions section. As the word "hectare" derives from "hecto-" plus "are", shouldn't this be the other way around? Isn't the hectare defined as 100 ares? Jimp 12Oct05

[edit] how many squared kilometers?

The article states that a hectare = 0.1 k^2. However, a hectare = (100 . 100)m^2 = 10^4 m2, while a squared kilometer = 1000^2 m2 = 10^6 m2. So I think a hectare is one hundreth of a squared kilometer. I'm going to change it into the article. S Sepp 17:41, 14 August 2006 (UTC)

Well spotted - it was recently wrongly changed to 0.1 by an anon (diff). Thanks for correcting it. -- ALoan (Talk) 17:58, 14 August 2006 (UTC)

Not necessarily vandalism though, might have been an honest confusion between 0.1 square kilometres and 0.1 kilometres square which mean different things. Femto 19:08, 14 August 2006 (UTC)

Perhaps. It is the area of a square of side 0.1 km, but "One hectare is equivalent to ... 0.01 square kilometres" is pretty clear, IMHO. -- ALoan (Talk) 19:18, 14 August 2006 (UTC)
