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.
These are units that indicate a very small amount of the substance being measured. Generally air or water contaminates are measured in ppm or ppb. ppm = parts per million ppb = parts per billion Concentration of carbon monoxide in underground carparks could be measured in ppm. Amount of contaminate in air could be ppm or ppb. Amount of cyanide gas? Amount of nutrient in soil or water? Amount of ozone in water purifying treatment facilities...
Uranium is not so rare: Earth crust: 2,7 ppm Sea water: 3,2 ppb Sun and the solar system: 18 ppb More than 200 minerals with uranium are known.

PPB stands for parts per billion and is used to measure the concentration of a substance in a mixture. PPM stands for parts per million, and is another unit of measurement like ppb, but represents a higher concentration in a mixture.
ppb is not a weight, but a ratio. "parts per billion"
1ppm is greater than 1ppb. Reason: ppm is mg/l and ppb is ug/l. And mg is always greater than ug. 1ng = 1000ug 1ug = 1000mg 1mg= 1000kg.... Hope this information helps. Regards, Nazia Farooqui Heriot Watt University, Scotland.
PPM-Parts Per Million: Number of grams of solute per 1 million grams of solution. ppm=[mass of solute/mass of solution]*10 to the 6th power&PPB-Parts Per Billion: Number of grams of solute per 1 billion grams of solution.ppb=[mass of solute/mass of solution]*10 to the 9th power.Hope this helps.
58 ppb = .058 ppm
Crustal rocks: 2-3 ppm Sea water: cca. 3,3 ppb

To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
abundance of uranium in the earth crust; 2,5-3 ppm (mg/kg) abundance of uranium in the sea water: ca. 3 ppb (?g/kg)
