How long is a piece of string?

Often used as answer for when there is no answer; usually like .... "when will you take the junk in basement, to the dump?"  How many times will George Bush mispronounce words?  So when Doc Schoozenbootzen said in response to my good news about the Shave....(he was clapping by the way) " that's good now your next assignment is the 30,000 Steps for Autism", it posed a question in my head.

How many steps in a kilometer? 

The Doc wants me walking an additional 6 km a day and that will burn off 1kg of Fat in a month. he thinks that will be good training. I walk between 3000 and 8000 steps at work a day. These are the facts. Now to the pieces of string.

Newbie says a person should be walking 10,000 steps a day just to maintain a good fitness. My friend the Science teacher rekons that the average person, when walking will travel .4 to .7 of a meter per step; for me he thinks .6 m/step. Now the Doc, yesterday, added that the organizers of the 30k step deally think its about 27K  It doesn't take a math genius to figure out that.
