How much is a part per trillion?

A concentration of one part per trillion means that there is one part of that substance for every one trillion parts of either air, water or soil in which it is contained. One part per trillion is equivalent to one nanogram per kilogram.

What does 1 part per trillion look like?

“A lot of times the analogy used to describe parts per trillion is drops in an Olympic-sized swimming pool. A part per trillion is one droplet of water in that pool,” she said. “So 140 parts per trillion would be about 140 droplets.”

What is ppt to PPM conversion?

1ppm = 106ppt. The number of parts-per million xppm is equal to the number of parts-per trillion xppt divided by 106: xppm = xppt / 106. Example: 7000ppt is equal to 0.007000ppm: xppt = 7000ppt / 106 = 0.007ppm.

What would part per trillion ppt equal to?

One part per trillion (ppt) denotes one part per 1,000,000,000,000 (1012) parts, and a value of 10−12. This is equivalent to about thirty seconds out of every million years.

Why do we use ppm?

Why is the PPM Measurement Important? In water treatment, we use ppm to measure the amounts of minerals and gasses dissolved in water. We use water as a medium to transfer heat. As the water transfers heat, these dissolved impurities in ppm can cause problems in the equipment such as mineral scale and corrosion.

Which is bigger ppm or ppt?

It is important to know that 1000 PPM = 1.0 PPT. They are the same measurement made different by only 3 decimal places. So for example, if you get a reading of 1.86 PPT, that would be 1860 PPM.

What are parts per billion?

Parts per billion (ppb) is the number of units of mass of a contaminant per 1000 million units of total mass. Also µg/L or micrograms per liter. Source: GreenFacts. More: ppb (or ppbm) is used to measure the concentration of a contaminant in soils and sediments.
