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.

What is ppm by volume?
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
Is uranium commonly found?
Uranium concentration in the earth crust: ca. 2,5 ppm (mg/kg) Uranium concentration in the sea water: ca. 3 ppb (micograms/kg)
What is the difference between mcg and ppm?
what is the difference between mcg's & ppm's? If you have 22 ppm's, how many mcg's would you need?
How common is iodine on earth?
The average relative abundance of iodine in earth's crustal rocks is 80 ppb, count of atoms, or 490 ppb by weight.
What is ppm-ppb-ppt used to express?
ppm = parts per million, eg. 1ppm = 1 part out of 1 000 000 = 1/1*106ppb = parts per billion, eg. 1ppb = 1 part out of 1 000 000 000 = 1/1*109ppt = parts per trillion, eg. 1ppt = 1 part out of 1 000 000 000 000 = 1/1*1012
What do the acronyms ppb and ppm represent?
ppb: parts-per-billion ppm: parts-per-million ppb and ppm are the ways of quantifying small concentrations, usually mass.
What is 28 ppb equal to in ppm?
0.028 ppm
What is the composition of the atmosphere on Mars?
95.32% carbon dioxide2.7% nitrogen1.6% argon0.13% oxygen0.08% carbon monoxide210 ppm water vapor100 ppm nitric oxide2.5 ppm Neon850 ppb HDO300 ppb Krypton130 ppb formaldehyde80 ppb xenon30 ppb ozone10 ppb methaneNote: ppm stands for parts per million while ppb stands for parts per billion. 210 ppm of water vapour means water vapour makes up 210/1,000,000 of the atmosphere.
How much does 15ppb weigh?
ppb is not a weight, but a ratio. "parts per billion"
What kind of atmosphere does Mercury?

How do you convert parts per billion to parts per million?
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.
How many parts per million is 58 parts per billion?
58 ppb = .058 ppm
How common is uranium in the earths crust?
Crustal rocks: 2-3 ppm Sea water: cca. 3,3 ppb
What does PPM in water means?
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...
Which is larger 1 Ppm or 1 Ppb?
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.
Is uranium common easily found?
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.
What is ppm by volume?
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
