100V-Line Speaker Cable Length for Given Load Power, mm2 & SPL Reduction

Calculates speaker cable length (metres) for the given load (W), cable CSA (mm2), sound pressure level (SPL) reduction (dB), and copper conductivity 'rho' (mOhm mm). The safety margin provides some additional assurance for the solution as volts drop is asymmetric in that 'it only gets worse' (ie you...

Conductor Size: AWG <> MM2 Conversion

Here is a solver program for converting between AWG and MM2 conductor sizes. EDIT: The 'magic numbers' in here all come from the definition of AWG, but with metric conversions: https://en.wikipedia.org/wiki/American_wire_gauge 00 { 50-Byte Prgm } 01▸LBL "AWG" 02 MVAR "AWG" 03 MVA...
