PTB to PPM Conversion

1 pound = 453.592 gm
1 Barrel =158.987 lit
1 PTB =1 pound / 1000 barrel
=453.592 gm / 1000 * 158.987 lit
PPM = mg / Litre
=(453.592 *1000) mg / (1000* 158.987) lit
Therefore =(453.592 *1000) mg / (1000 *158.987)lit
=453592 mg / 158987 lit
1 PTB =2.8530 PPM
1 PPM =0.3505 PTB

    MR.SHANKAR.

    KINDLY TELL ME WHETHER CRUDE DENSITY PLAYS A ROLE IN DETERMINING THE PPM
    SUPPOSE MY CRUDE DENSITY IS 0.838 AND 0.890 WHETHER MY PPM WILL BE SAME AS YOU SAID
    1 PTB=2.85 PPM

    Thank yoy for sharing information.But why ppm is mg/liter? ppm is just a pars per million. if the denisty is 1000 kg/m3, it is okay. but if not...it may be not correct. Please explain

    If you are reporting mg/L as ppm, then the calculation is already in mass/unit volume, so sp.gravity will not affect the value.

      Same equation: (198,000 ppm x 0.3505 = 69,399 PTB)
