Formula:
Our Air Duct Calculator provides essential calculations for both rectangular and round duct types:
- Rectangular Duct Formulas:
- Surface Area =
2 * (Width + Height) * Length - Volume =
Width * Height * Length
- Surface Area =
- Round Duct Formulas:
- Surface Area =
π * Diameter * Length - Volume =
π * (Diameter / 2)2 * Length
- Surface Area =
Where π (Pi) ≈ 3.14159, and all dimensions (Width, Height, Diameter, Length) are in the same unit.
