Particulate testing of compressed air
Particulate testing of compressed air
(OP)
Hey folks, wondered if anybody could help. I am currently project managing a compressed air system test(for breathable air). I have a met one laser particle counter which is giving me particle counts in microns/cubic feet (u/ft3). However the client would prefer the results presented in u/m3. I have obtained a conversion factor for cubic feet to cubic metres, multiply by 0.0283(i.e. divide by 35.315) but the client seems to think that the u/ft3 needs to be multiplied by 35.315. I was wondering if anybody has dealt with particulate testing of compressed air, and where i could get confirmation in writing of the correct conversion factor to use.

Your client is correct....multiply your value by 35.315
RE: Particulate testing of compressed air
NOTE: Conversion factors- mppcf x 35.3 * million particles per cubic meter

Hello Pearse,
The standard conversion from cubic ft to cubic meter is a multiplier of 0.02831685. This is a standard conversion like converting liters to gallons. Any conversion program or spreadsheet that has volume conversion will give you this result. Hope this helps.

In this case the manufacturer has it exactly backwards, which didn't make you look very good to your client. You might want to point that out to them.
I won't go on a rant about metric conversion...we should have been there long ago, but we're not.
Measure twice, cut once.
