Hello. I am new to engineering and to imperial units, and currently learning by doing some exercises. I'm stuck on the following conversion:(adsbygoogle = window.adsbygoogle || []).push({});

- 0.04 g / min x m^3 -> lbm / hr x ft^3

I figured it like this:- 0.04 g / min x m^3 x (60min/1hr) x (1m/35,314)^3 x (1 lbm / 454g) =

1,49x10^-4 lbm / ft^3 x hr

However, the author of the book gives the following solution:

- 0.04 g / min x m^3 x (60min/1hr) x
(12in/1ft)^3x (1 lbm / 454g) =

9.14 lbm / ft^3 x hr

It really lost me, why (12in/1ft)^3 its supposed to cancel out m^3? He does the same on a similar exercise converting cm^2 with (12in/1ft)^2.

Thanks for your time and help.
