The term "km2" is usable in written English and is well written.
It is typically used to denote square kilometers, a unit of area measurement. Example: "The area of the national park is approximately 500 km2." Alternatives include "square kilometers" or "sq km."
The first, in 1998, found that the massive (2,600 km2) Tucurui reservoir emitted 76 tonnes of methane per km2 and 3,808 tonnes of carbon dioxide each year; but a second study last year put the figures at a mere five tonnes of methane and only 2,378 tonnes of CO2.
Ultra-high-energy neutrinos travelling through the ice are thought to interact with it and produce Cherenkov radiation about once per century per km2, so an area of this size would be expected to yield about 40 bursts a day.
Reflecting the attraction of this combination, the Cumbrian districts of Copeland and Allderdale were ranked first and third in the list, and are the least densely populated districts in the country, with less than 100 people per km2.
We scored some data on yearly harvested area, production weight and wholesale value for the most common food crops from the UN Food and Agriculture Organization, and used it to calculate yield per km2.
"The grey squirrel population has crashed in approximately 9,000 km2 of its former range and the red squirrel is common after an absence of up to 30 years".
The South Africa 2010 World Cup saw 145 balls in nets, which would translate to 1450 km2 or around 0.2% of the region (corrected from original post, in which I got my maths muddled).
