I have 1200 ft^3 of space. We recently recorded the air quality as 162 micrograms/m^3 for particulate matter smaller than 2.5 microns (PM2.5).If the air in your space had the same AQI, how many grams of particulate matter are present?

Answer 1

To find the grams of particulate matter present in your space, we need to convert the air quality measurement from micrograms/m^3 to grams.

First, convert micrograms to grams:
1 microgram = 0.000001 grams

Now, convert cubic feet to cubic meters:
1 ft^3 = 0.0283168 m^3

Thus, the total volume of your space in cubic meters is:
1200 ft^3 * 0.0283168 m^3/ft^3 = 33.9816 m^3

Next, multiply the air quality measurement by the total volume to find the grams of particulate matter present:
162 micrograms/m^3 * 0.000001 grams/microgram * 33.9816 m^3 = 0.0055004632 grams

Therefore, there are approximately 0.0055 grams of particulate matter present in your space with the same AQI.
