ppb to micrograms per metre cubed
by cheryl_williams on 04/13/05 at 07:36:56

Could you set up a conversion for ppb to microgram per metres cubed?

I wish to convert a concentration of benzene in air.

I have been told that 1.54 ppb is 5 microgram per metres cubed.  Is this correct?

Thanks,
Cheryl

Though you are converting to ug/m[sup]3[/sup] instead of ug/L, just multiply ug/L by 1000 to get ug/m[sup]3[/sup]

at 20 degree centigrade the conversion factor for benzene from microgram to ppb is 0.317 and at 25 degree centigrade the conversion factor is 0.313
