What is the typical electrical conductivity of marketed powdered graphite products over a distance of 1cm?

I'm trying to suss out how some powder graphitic material I processed compares to marketed graphite products in regards to electrical conductivity.
The way I tested was by placing the powder in a filter, flushing it and letting it air dry. This resulted in a fairly compacted material which I then
probed with a multimeter, placing the pins 1cm apart for a prolonged and stable reading of 14.4ohms.

How does that compare with what's out there in the world?

You didn't provide sufficient information. Resistance will be related to the dimensions of your chunk of graphite. Not that I'm inclined to do your research for you..

yes, shape and material composition will all be factors. resistance will be low - few Ohms ad not kOhm or MOhms. your value is a representative of what to expect. i remember fun as a kid learning about electricity. we would extract graphite from pencil to make a crude version of carbon microphone. worked like a charm.
