Nickel is an element. Therefore, in any nickel item it is 1 billion parts per 1 billion or 1 million parts per million.
parts per million = ppm
1% is 10,000 parts per million.
10,000,000 (ten million) thousands per 10 billion.
I is ot possible. You need TWO measures to convert to parts per million.
0.0035% Parts per million can be converted to parts per hundred by dividing by 10,000 or setting up a proportion. 35 ppm = 0.0035 parts per hundred. hence percentage it is 0.0035%
50ppb is equal to 0.05ppm
48.5ppb equates to 0.0485ppm
58 ppb = .058 ppm
Parts per Million and Parts per Billion. Parts of a solute per Million parts of the Solvent.
There are 1,000,000,000 micrograms in a kilogram. This actually means parts per billion. Parts per million would be mg/kg. So to get here, you need to divide by 1000.
300ng/ml is 300 micrograms per litre which is the same as 300ppb (parts per billion), or 0.3ppm (parts per million)
ppm by volume is "parts per million" by volume as opposed to ppm by weight. ppm by volume and ppm by weight are not the same thing It has been suggested that the drinking water in West Hampshire be adultery with 1 ppm by volume of fluoride. This is an example of ppm by volume
ppb: parts-per-billion ppm: parts-per-million ppb and ppm are the ways of quantifying small concentrations, usually mass.
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
parts per million = ppm
