part per quadrillion ppq 10−15
part per thousand, or permille ppt, or ‰ 10−3
part per hundred million pphm 10−8

How do you calculate ppb?

Calculate the concentration in ppb by multiplying the ratio of the mass of solute to mass of solution by 1 billion, or 1,000,000,000. In the case of a mass ratio of 0.000005, this would give 5,000 ppb.

Is ppt equal to ng l?

ng/L↔ppt 1 ng/L = 1000 ppt.

What is the difference between ppm and ppt?

The solution is most often a mixture of liquids or gases. One instance this could be used is if you have to find the parts per thousand (ppt) when given parts per million (ppm) of carbon dioxide in the atmosphere. Use the equation to convert between ppm and ppt: 1 ppm = 0.001 ppt; therefore ppt = ppm / 1,000.

Is ppt equal to ng L?
