I have 1200 ft^3 of space. We recently recorded the air quality as 162 micrograsm/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? And you can only use the conversion below:

1 in = 2.54 cm
1m = 39.4 in
12 inches = 1 foot
1km = 0.621 mi
1lb = 454 g
1 oz = 28.3 g
1 quart (qt) = 0.946 L
1 mL = 0.034 Fluid ounces (fl oz)
0.265 gallons = 1 L
1 cm3 = 1 mL
1 micron = 1 micrometer
60 seconds = 1 min
60 min = 1 hr
24 hrs = 1 day
7 days = 1 week
365 days = 1 year
109 nm = 1m
106 micrometer = 1m
1000mm = 1m
100cm = 1m
10dm = 1m
1 km = 1000m
109 nm = 1 m
109 nL = 1L
109 ng = 1g
1000 mm = 1m
1000 mL = 1L
1000 mg = 1 g

To convert the air quality measurement from micrograms per cubic meter (µg/m³) to grams in your given space, we need to follow these steps:

1. Convert the volume of the space from cubic feet (ft³) to liters (L):
1 ft³ = (1 ft)³ = 1 ft × 1 ft × 1 ft = 12 in × 12 in × 12 in = 1728 in³
1 in³ = (2.54 cm)³ = 16.387 cm³
1728 in³ × 16.387 cm³/in³ × (1 L / 1000 cm³) = 28.3168 L

2. Convert the air quality measurement from µg/m³ to g:
162 µg/m³ × (1 g / 1000 µg) = 0.162 g/m³

3. Calculate the total grams of particulate matter in the given space:
28.3168 L × 0.162 g/m³ = 4.5872 g

Therefore, there are approximately 4.5872 grams of particulate matter present in your 1200 ft³ space with the same air quality index (AQI).
