The same equations may be used to convert micrograms per cubic meter (ug/m3) to parts per billion (ppb) and vice versa: Concentration (ug/m3) = 0.0409 x concentration (ppb) x molecular weight Or, concentration (ppb) = 24.45 x concentration (ug/m3) ÷ molecular weight Here is an example. The molecular weight of benzene is 78.

What is the difference between mg/m3 and ppb?
Likewise, one milligram per cubic meter (mg/m3) is the same concentration in water as one microgram per liter (ug/L), which is about 1 ppb.
How do you convert ug/m3 to PPPB?
The same equations may be used to convert micrograms per cubic meter (ug/m3) to parts per billion (ppb) and vice versa: Concentration (ug/m3) = 0.0409 x concentration (ppb) x molecular weight Or, concentration (ppb) = 24.45 x concentration (ug/m3) ÷ molecular weight Here is an example. The molecular weight of benzene is 78.
What is the difference between ug/L and ppb?
13 mg/m3 = 13 ppb. 14 mg/m3 = 14 ppb. 15 mg/m3 = 15 ppb. 16 mg/m3 = 16 ppb. Secondly, is ug/l the same as PPB? Likewise, one milligram per cubic meter (mg/m3) is the sameconcentration in water as one microgram per liter (ug/L), which is about 1 ppb.
What is the relationship between ppm and ug/L?
other using this relationship: 1 part per million = 1,000 . parts per billion. For water, 1 ppm = approximately 1 mg/L (also written as . mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also . written as ug/l). A measurement of 6 mg/L is the same as . 6 ppm or 6,000 ppb, which is equal to 6,000 ug/L. .
Is ug the same as ppb?
For water, 1 ppm = approximately 1 mg/L (also written as mg/l) of contaminant in water, and 1 ppb = 1 ug/L (also written as ug/l). A measurement of 6 mg/L is the same as 6 ppm or 6,000 ppb, which is equal to 6,000 ug/L.
Is UG m3 the same as ppm?
Thus, mg/m3 represents milligrams (one-thousandth of a gram) per cubic metre of air, while µg/m3 stands for micrograms (one-millionth of a gram) per cubic metre of air. However, these concentrations can also be expressed as parts per million (ppm) or parts per billion (ppb) by volume through a conversion factor.
What does µg m3 mean?
microgramsHelpCenter Definition. The concentration of an air pollutant (eg. ozone) is given in micrograms (one-millionth of a gram) per cubic meter air or µg/m3.
What is ppb equivalent to?
PPB stands for "parts per billion" and it is used to measure the concentration of the solution(mole fraction or mass fraction). One ppb is equal to 1 µg/l.
How do you convert micrograms to ppb?
ug/mL↔ppb 1 ug/mL = 1000 ppb.
How do you convert ppb to mg m3?
ppb↔mg/m3 1 ppb = 1 mg/m3.
What is ppb air quality?
parts per billionOn Oct. 1, 2015, the U.S. Environmental Protection Agency (EPA) strengthened the National Ambient Air Quality Standards (NAAQS) for ground-level ozone to 70 parts per billion (ppb), based on extensive scientific evidence about ozone's effects on public health and welfare.
What does PM 2.5 mean in face mask?
particulate matterPM 2.5 filters are lightweight filters that can be placed inside a regular reusable mask to add more layers of breathable protection. PM stands for particulate matter, meaning they can filter out fine particles at 2.5 microns in diameter.
How do you convert ug m 3 to ppm?
Similarly, to convert from micrograms per meter cubed, divide the concentration by 1,000. A concentration of 30 micrograms per meter cubed therefore equals 0.03 PPM.
Is microgram per gram equal to ppb?
ug/g↔ppb 1 ug/g = 1000 ppb.
Is ppb a volume?
ppb (or ppbV) is often used to describe concentrations of contaminants in air (as a volume fraction).
Is ppm the same as ug mL?
ppm↔ug/mL 1 ppm = 1 ug/mL.
What Does mg/m3, µg/M3, Ppm, and Ppb Stand for?
How to Convert Between µg/M3– Ppb and Mg/M3– Ppm
- The formula for conversion between µg/m3(micrograms per cubic metre) and ppb (parts per billion) are as follows: Converting from ppb to µg/m3 is: Concentration (µg/m3) = molecular weight x concentration (ppb) ÷ 24.45 Converting from µg/m3 to ppb is: Concentration (ppb) = 24.45 x concentration (µg/m3) ÷ molecular weight The number 24.45 in the equationis the volu…
What Are The Conversion Factors For The Common Major Air Pollutants?
- Below is a table with the conversion factors and the molecular weights of the major air pollutantsfound to be the most damaging to human healthand to the environmentbased on the formulas above at 25°Cand 1 atm (standard atmospheric pressure): An exception to the conversion process is the air pollutant particulate matter (PM10 and PM2.5), as it consists of va…
