  • ug/kg, ug/L to ppm

    Does 1,000 ug/kg = 1 ppm? How many parts ppm is 1,800 ug/L?
    Does 1,800 ug/L = 1.8ppm? Thank You!

    Re: ug/kg, ug/L to ppm

    ppm stands for parts per million. There is 1000g in a kg, 1,000,000mg in a kg, and 1,000,000,000ug in a kg.

    1000ug/kg is therefore 1ppm

    1800ug/L is 1.8ppm.

    If you are talking about volumes, 1000mL = 1L, 1,000,000uL = 1L, so 1uL/L = 1ppm. - this is particularly important with gases.

      Thanks! So does 53,000 ug/kg = 53ppm? Is water 1,800 ug/L = 1.8 ppm? Very Appreciative

        Re: ug/kg, ug/L to ppm

        if each tablet has 800ug how many tablets would 1kg do?

        sorry am so confused with all ...

          Re: ug/kg, ug/L to ppm -- and to percent %

          thank you for the info to convert ug/kg to ppm

          if 1000 ug/kg = 1ppm, then 50ug/kg = 0.05ppm,...correct?

          what is 0.05ppm expressed as a percent?
          can you show me the equation? for the lay reader like me?

          thank you

            the equation is 0.05/1,000,000 x 100 = 5e-6%

            For problems such as this, you can always relate it to what "100%" MEANS.

            A pure substance is 1,000,000ppm.

              Re: ug/kg, ug/L to ppm

              If a liquid is 1800ppm and 3500ppm what is the % equivalent?

                Divide by 10000 to convert ppm to percent, so
                0.18% and 0.35%.

                  Hello,

                  I have a doubt about the conversion if I have the result as bellow:

                  221 ug/kg = ?? PPB

                  It's urgent, I'll be gratefull with if someone could answer correctly to me.

                  rgds,

                    rgds,
                    Micrograms and kilograms differ by 10^9, so if ppm by weight is what you want, 221 µg/kg = 221 ppb w/w

                    Parts per million (or billion) can also be ratios of volumes or moles.

                      Re: ug/kg, ug/L to ppm

                      so 12 ug/L = 0.0012PPM?

                        One too many zeroes. 12 ppb (parts per billion or 0.012 ppm

                            Listen when working with ug you are using the 1,000,0000 that's billion. This conversions are straight forward in this case just put the billion up and put the ug number under it.

                            Or
                            ug 221 is

                            1,000,000,000
                            221
                            when using the micro gram that part is to what ever it is to a billion. And this is all based on the kilogram or kg. or only 221 ppb. Hope that helps.

                              I have purchased some colloidal silver at a strength of 14,000ug/l

                              Can anyone tell me how many parts of colloidal silver would be contained in a 100ml dose ???

                              Cheers guys
