There are 100 hectares in 1 square kilometer (remember, a square 1 hectare field has 100 meter [0.1 km] sides).  An inch is 25.4 mm and 2.54 cm.  25 mm is an acceptable rough inch equivalent for estimation.  --  Jason ----- Original Message ----- From: john mercer To: U.S. Metric Association Sent: Friday, September 05, 2003 12:07 PM Subject: [USMA:26858] More Questions Hello everyone I just want to thank everyone for answering all my questions.  I have another couple of them.  How many Hectares are there in a square kilometer? If a person asks me how many Cm's are in an inch should I tell them 2.5 or 2.54? I know that 2.54 is the exact conversion but is 2.5 good enough for every day use?  If I explain the metric system to someone who isn't used to it and wants to know the conversion factor I don't want to make the metric system seem dificult.  I know that Usma doesn't support conversion because it can make the metric system seem mor dificult than it is.  However when we explain the metric system using a measurement they are used to it might help.  I agree having dual sided rulers and meter sticks only slows the progress of going  metric.  Thanks again for all your help John Mercer.
