infuriating fact: 0402 metric = 01005 imperial, 0402 imperial = 1005 metric. looks like this is the only semi-duplicate in common use.

And that's how I ended up with half a reel of 01005 resistors...

Wait wait wait what? 01005 isn't metric? They switched to imperial for just that size? What?

    I was a bit outdated with resistor sizing and I don't have a great sources but apparently there are:

        inch 0402, 0201, 01005, 009005, 008004, $1
    mm   1005, 0603, 0402,  03015,  0201,   01005
    these sizes... and $1 is the one in your mind that shall not be written in inches. The "01005 imperial" is just 0402, so it's not going up to the metric 01005 scale or beyond. I think.
