Re: Converting Henries to KHZ.
wow .. i need to dust off my electrical engineering knowledge for this one .. to start, you can't change henries (a unit of inductance) into herz (a unit of frequency) ... and to add more info to the answer, neither henries nor herz tell you about 'hotness' of a pickup ... some folks roughly equate the DC resistance of a pickup to its 'hotness', but it is a crude measure because a pickup's DC resistance is only a valid measurement in a DC circuit, and when a pickup is working it is part of an AC circuit ... in order to make any meaningful inference of an AC circuit's performance, one needs to know the frequency .. for a guitar, that will be everything from a few dozen hertz to a couple handfuls of kilohertz
using a single number to figure out a pickup's 'hotness' is very dicey at best ... and a pickup cant make a 50 watt amp into a 100 watt amp no matter how it's wound :smile:
good luck

Well to be technical you can go from L (henry) to the resonance frequency. From there you can go to the DC resistance which can give you some info on the pickup hotness. I need to look up the precise formula's though, memory is a bit rusty and the formual's are somewhat complex.

Re: Converting Henries to KHZ.
You need to know the capatance from the winding. I can't remember the equation, but this website will calculate it for you. I'm not sure you've had that much Algebra since you're only 14 (no offense).

This place DGB Studio has some real technical aspects of guitars. you guys oughta check it out, very cool!

Re: Converting Henries to KHZ.
If I had to take a guess, the winding capatance is .0001 microfarads, rounding it out to 5.247 Khz for a resonant freq.

Re: Converting Henries to KHZ.
This is too simple.
If you want to know the DC resistance, measure it.
Beats the hell out of doing math. The inductance and res. freq. wont be terribly helpful in guestimating output, knowing the DC resistance and magnet type will give a good indication.
