Hi,
I would like to know if there is a relationship other then between cm and henries in an inductor: Here is a link where a tesla coil is made and measurements are made in cm and converted in Henries. Any can illuminate me on this ? First example on top of this link
Have a great day

My guess is that it's just a units thing. In the MKS system inductance is in Heneries. In the cgs system the units are all weird, and it may be that inductance has 'units' of centimeters... I seem to recall that capacitance has units of inverse centimeters in cgs units.... I haven't touched cgs units since doing JD Jackson back in the dark ages. You might try googling inductance and units conversion.

In Gaussian units (as well as ESU and EMU) capacitance has units of cm, resistance has units of s/cm, and inductance s^2/cm . See, for example,
It's not clear to me just what the author of that document (supposedly Tesla?) had in mind when he used units of cm for both capacitance and inductance. I note that he also specifies Farads and Henries and the conversions to cm seem to require only a shift of the decimal place. Very odd.
I also note that he was somewhat cavalier with his significant figures in the results; he's given measured values to a single digit and a result to seven, and this is after several roundings at intermediate steps.
...
,Ahh, Thanks Greg... my mistake. (no matter what LC should have units of inverse seconds squared.) So the author of the document (Tesla, really?) has screwed up the units?
To the OP, There are lots of Tesla websites out there you could try asking at one of those.

Yes there is a relationship. cm or centimeter was used at one time for the electromagnetic cgs unit of inductance. This is also known as an abhenery. 1 abhenery (cm) = 10^-9 henrys.
You can see this relation in their numbers: 0.00955 = 9,550,000 * 10^-9 Nine millihenrys = 9 million abhenrys or cm.
The rationalized MKS system (SI) has done away with abhenrys, abvolts, stathenrys, statfarad and other confusing nonsense of the cgs system. See, the metric system isn't as simple as you thought.
