Round or oval ducts have advantages over rectangular ducts and this calculator app makes transitions easier.
The Eastern Sheet Metal Rectangle to Round Duct Calculator App is used by sheet metal contractors and installers, HVAC engineers and contractors to quickly convert the following duct diameters: rectangular to round, oval to round, or rectangular to oval using the U.S. customary system (inches, feet, etc.).
Duct equivalent diameters and properties will include CFM, inches, and water gauge. As measurements are entered into Eastern Sheet Metal’s Rectangle to Round Duct Calculator app, the equivalent round diameter, air velocity, friction rate, and its total friction are calculated in seconds.
