Try out each conversion, and see which leads to round numbers. To expand on Jim's factor:
1 ft3/min = 0.471 947 4 L/s = 28.316 84 L/min = 1.699 011 m³/h --- On Fri, 3/18/11, Remek Kocz <[email protected]> wrote: From: Remek Kocz <[email protected]> Subject: [USMA:50081] Re: PC Case fans & flow measurements To: "U.S. Metric Association" <[email protected]> Date: Friday, March 18, 2011, 12:13 AM Because I'm not sure what's used in the metric world of airflow measurement. I recall seeing maybe cubic meters per hour, but I know for sure that it wasn't L/min. On Thu, Mar 17, 2011 at 5:25 PM, James R.

Whereas in the past it used to be that the cubic foot per minute numbers were fairly round and elegant, these days they've become strange, with up to two figures past the decimal point. I can assume that the Asian manufacturers began insisting on the metric terms, and these oddball CFM's are the conversions. Any ideas? -- James R.
