According to my copy of the
Starfleet Technical Manual, published by Franz Joseph back in 1975, warp factor was the
cube of the speed of light. E.g warp 1 was the speed of light, (1 x 1 x 1) = c, warp 2 was (2 x 2 x 2) 8 times the speed of light 8c, warp 3 was 27c warp 4, 64c, and so on.
I don't think it's canon, and it certainly was never made explicit in the original series. Actual velocities and distances were intentionally kept vague. I'm pretty sure it's been contradicted in other non canon material too. Famously, Roddenberry made up an equation to explain the distances and speeds which he put in the series bible, intending to look up the actual equations involved and replace it, but never did.
And then TNG overturned it all, making warp 10 infinite speed, much as the speed of light itself is to us today.
So much for the minutiae of
Star Trek technicalities!
