Re: [MW:35714] PPM to mg/m2 conversion

 3000ppm =   50μg/cm²

(As per Elcometer kit 130 datasheet. Ref:- https://www.elcometer.com/en/elcometer-130-salt-contamination-meter.html)

1 μg/cm² = 10mg/m²

Gents,

Is there any conversion available for ppm to mg/m2?

For Aramco projects, the chloride content measured in ppm using bresle patch kit in ppm.

As per Aramco spec the acceptable range is 20mg/m2.

Couldn't find the conversion. If anybody can advice, it will ne highly appreciated

Reg,

Ibrahim
