0.04 percent is 400 per million.
50 ppm is 0.005%
20000 ppm = 2%
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
Yes, 0.5 ppm is 0.00005%
Divide ppm by 10,000:50,000 / 10,000 = 5 %
It should be at least 99.5 percent CO2.
To convert 10% CO2 to parts per million (ppm) CO2, you need to multiply by 10,000. Therefore, 10% CO2 is equivalent to 100,000 ppm CO2.
We won't asphyxiate. But CO2 is a heat trapping gas, and it takes decades for the earth to adjust to any slight rise. Human activity has increased CO2 levels from 280 ppm prior to the industrial revolution to nearly 400 ppm today. We will pass 500 ppm before 2050, at the current rate. Many climate scientists believe 350 ppm may be the maximum sustainable level for CO2.
The amount is increased. Co2 is a greenhouse gas.
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
Ppm stands for parts per million. It is a way of showing the amount of one substance in another, like carbon dioxide in the atmosphere, especially when the percentage number is small. For example, in July 2011, the amount of carbon dioxide in the earth's atmosphere was 392.39 ppm (or 0.039239%).
0.1 percent = 1,000 ppm 1 percent is 10,000 ppm. 2 percent is 20,000 ppm 3 percent is 30,000 ppm 10 percent is 100,000 ppm etc. Take the percent, move the decimal point 4 places to the right, and you have the ppm. You take it from here.
46 ppm is 0.0046%
0.110 ppm = 0.000011%
To convert 0.06% selenium to ppm, you need to multiply by 10,000. Therefore, 0.06% selenium is equivalent to 600 ppm. To convert 600 ppm to 90 ppm, you would need to dilute the solution by a factor of 6.67 (600 ppm / 90 ppm).
To calculate the parts per million (ppm) of CO2 in the air, you would measure the concentration of CO2 in the air using a CO2 sensor or monitor, and then divide that by the total volume of the air sample. This would give you the ppm of CO2 in the air sample. Common methods include using infrared gas analyzers or chemical absorbents.
A CO2 probe sensor measures gaseous carbon dioxide. It comes in two ranges, 0 to 10,000 ppm and 0 to 100,000 ppm.
