Description: Area
A Two-Dimensional Quantity
• Area measurements utilize linear measurements
to calculate the number of unit squares within a
given boundary.
• Measurements of area are expressed in “square
units” such as square inches, square feet, square
meters, etc.
• They have length and width but thickness is not
considered in the calculations.
• Never mix units in the same calculation.

1 square foot = 144 square inches
1 square yard = 9 square feet = 1,296 sq. in.
1 cubic foot = 1,728 cubic inches
1 cubic yard = 27 cubic feet = 46,656 cu. in.
1 cubic foot = 7.47 gallons of water*
1 gallon of water = 8.3453 pounds*
1 square centimeter = 100 square millimeters
1 square meter =10,000 sq.cm.=1,000,000 sq.mm
1 cubic meter = 1,000,000,000 cubic millimeters
1 cubic meter = 1,000 liters of water*
1 cubic meter = 264.2 gallons of water*
1 liter of water = 1.000 Kilogram*

Exhaust Fan Calculations
• NC Mechanical Code Requirements for
Exhaust Fans:
– Autopsy Room: .50 cubic foot per min. per sq. ft.
– Pet Store: 1 cubic foot per minute per square foot
– Smoking Lounge: 60 cu.ft. per min per person
• Exhaust Fan Specifications:
– Economy Model: 60 Cubic Feet per Minute (CFM)
– Commercial Model: 50 CFM
– Commercial Model: 80 CFM

Exhaust Fan Questions
1 If the room in question were to be used as a pet
storage facility, which exhaust fan would be
needed?
2 If the room in question were to be used as to
perform autopsies, which exhaust fan would be
needed?
3 If the room in question were to be used by a
person who will be smoking in their office,
which exhaust fan would be needed?

Room Calculations
Inside Dimensions: 96” wide x 102” long
96” x 102” = 9,792 sq.in. divided by 144 sq.in. = 68 sq. feet
(8ft. x 8.5ft. = 68 square feet)
Inside Dimensions: 96” wide x 102” long x 99.5” high
96” x 102” x 99.5” = 974,304 cu.in. divided by 1,728 cu.in.
= 563.8 cubic feet
(8ft. x 8.5ft. x 8.3ft. = 564.4 cubic feet)
Industrial Applications:
Exhaust Fan Questions
1 If the room in question were to be used as a pet
storage facility, which exhaust fan would be
needed? (80 CFM)
2 If the room in question were to be used as to
perform autopsies, which exhaust fan would be
needed? (50 CFM)
3 If the room in question were to be used by a
person who will be smoking in their office,
which exhaust fan would be needed? (60 CFM)
