electrical engineering uses some weird units sometimes
- the mil (0.001 inch), used for PCB layout and device package dimensions
- the μ" (0.001 mil), used for plating thicknesses
- the circular mil (π/4 square mils), used for wire cross-sectional area
- the MFT or kilofoot (1000 ft), used when specifying cable resistance (in Ω/MFT)
- the □ (square), as used in Ω/□, for measuring surface resistivity
- the √Hz (root hertz), used for measuring noise spectral density (as nV/√Hz)
-F/R
@Felthry I'd seen most of those. Circular mill is pretty funky.
But root hertz is making me 0_o
