Difference Between μg ,mcg or ppm

Difference Between μg ,mcg or ppm

All are same, why we can say all are same

Tri to understand as following

μg    =  one millionth (1×10⁻⁶) of a gram,

       = one gram/1000000 = 0.000001g or 0.001mg

mcg =  one millionth (1×10⁻⁶) of a gram

       = one gram/1000000 = 0.000001g or 0.001mg

ppm =  ppm (parts-per-million)

           one millionth (1×10⁻⁶) of a gram.

        =one gram/1000000 = 0.000001g. or 0.001mg

So, we can say that the μg ,mcg or ppm are same.

For example :We want to make 100ml of 10 μg/ml dilution.

           = 10 x 0.000001g(μg)= 0.00001g/ml or 0.01mg/ml.

              For 100ml = 0.01mg x 100ml or 1.0 mg/100ml   

For example :We want to make 100ml of 10 mcg/ml dilution.

           = 10 x 0.000001g(mcg)= 0.00001g/ml or 0.01mg/ml.

              For 100ml = 0.01mg x 100ml or 1.0 mg/100ml 

For example :We want to make 100ml of 10 ppm dilution.

           = 10 x 0.000001g(ppm)= 0.00001g/ml or 0.01mg/ml.

              For 100ml = 0.01mg x 100ml or 1.0 mg/100ml
