That is a fair point Scott. I'll add extra information. :)

What do you think now @scottkellum: http://sass-guidelin.es/#units?

[scottkellum]

@hugogiraudel Looks good. Note that + 0px behaves a bit differently and will not convert another compatible unit.

0px + $value is more robust because

1in + 0px = 1in
while
0px + 1in = 96px

idk, maybe that gets into the weeds a bit. For a simple guide like this I’d probably just recommend $length: $value * 1px; and omit $length: $value + 0px;

Actually I like that. I might add it. :)
