Talk:Square kilometre

Value in acres

I was checking the values listed on this page. The page currently says that 1 sq km equals 247.105383 acres.

The GNU units program gives 247.10439 acres

The National Oceanographic Data Center say 247.105381 acres [1]

The Google calculator also says 247.105381 acres [2]

I think 247.105381 is probably right. It is a pretty minor thing but it would be good to get it right. I will try to do some more checking, but welcome any comments from others. -- Popsracer 11:21, 29 Sep 2003 (UTC)

1 sq km = 1,000,000 sq m

0.3048² sq m = 1 sq ft

16.5² sq ft = 1 sq rod

160 sq rods = 1 acre

1 sq km = 247.105381467 acres

er... I think... Evil saltine 11:44, 29 Sep 2003 (UTC)

GNU Units assumes the U.S. survey acre instead of the international acre. The figure 247.105383 has an error in its last digit. -- Indefatigable 16:58, 30 Sep 2003 (UTC)

That's why the metric system is the best. A metre is a metre is a metre, and a kilometre is a kilometre is a kilometre. None of this business of having to remember whether you're British or American, land-based or nautical, civilian or military, and so on. JIP | Talk 18:30, 22 September 2008 (UTC)

Oh yeah. metric system is the best.78.106.148.243 (talk) 16:15, 3 February 2009 (UTC)
