0.3 m3/min/m2 equals how many cubic feet per minute per square foot (cfm/ft2)?

0.3 m3/min/m2 equals how many cubic feet per minute per square foot (cfm/ft2)?

• A. 0.5
• B. 1
• C. 2
• D. 5

Answer: (B)

Converting flow per area between metric and imperial units follows the same idea as any unit-forced ratio: change both the volume and the area to the desired units, then simplify. 0.3 m^3/min per m^2 times 35.315 ft^3 per m^3 gives 0.3 × 35.315 ≈ 10.5945 ft^3/min per m^2. Since 1 m^2 is 10.764 ft^2, this becomes 10.5945 ft^3/min per 10.764 ft^2, or 10.5945 / 10.764 ≈ 0.984 ft^3/min per ft^2. So the value is about 0.984 cfm/ft^2, which rounds to 1 cfm/ft^2.
