how much is 3.5 ppm 1000ppm in ounces?

Answer 1

3.5 ppm means 3.5 parts in 1,000,000 parts. It is a ratio, not a weight.

Answer 2

ppm is a scientific term for parts per million. Its just like percent, which means parts per hundred. Your question doesn't make any sense, as ppm is a ratio or a concentration and ounces are a unit of weight.

1,000,000 ppm = 100%
1,000 ppm = 0.1%
3.5 ppm = 0.00035%

I don't quite agree with Lindajune's answer, "if you have 3.5 ppm of salt, that would weigh a lot less than 3.5 ppm of uranium." While uranium does indeed have a much higher specific gravity than salt, that would depend on what consitutes the other 999,996.5 ppm. Even if it was, for example, water, the difference in total mass between a 3.5 ppm concentration of salt and a 3.5 ppm concentration of uranium in water, the difference in weight would be miniscule.

Let's suppose we have a 1 cubic meter container of water with a 3.5 ppm concentration of salt, and a 1 cubic meter container of water with a 3.5 ppm concentration of uranium. The SG of water is 1, salt is 2.16, and uranium is 18.7.

That means the salt solution weighs (999,996.5 x 1) + (3.5 x 2.16) = 1,000,004 grams, and the uranium solution weighs (999,996.5 x 1) + (3.5 x 18.7) = 1,000,061.9 g. That's not much of a difference!

Either way, its not possible to compare ppm to ounces, just like there is no correlation between gallons and feet or liters and temperature.

Answer 3

ppm = parts per million. ~
You would have to quote a quantity of liquid, before you can calculate how much 3.5 or 1000 ppm would be
In the case of 1000ppm, it would be 1/1000th of the total.

Answer 4

Parts per million is a measurement of numbers.
Ounces is a measurement of weight.
So if you have 3.5 ppm of salt, that would weight a lot less than 3.5 ppm of uranium.
So we'd have to know what the "stuff" is before we could answer.

So you didn't like the answers that the people gave in your other thread.. Did you even check the link that Yellow Green SeaGull posted??
