Description Duct Calculator is a professional HVAC utility designed to help engineers and technicians accurately calculate duct sizes and airflow values for ventilation systems. Built for real-world design and installation work, this app simplifies essential HVAC calculations and improves efficiency on the job. The app allows users to calculate required duct sizes using available airflow (CFM) and air velocity (FPM). Both rectangular and round duct sizes can be calculated in inches, making it suitable for a wide range of HVAC projects. In addition to duct sizing, Duct Calculator can also determine air flow rate in CFM and air velocity in FPM, helping professionals verify system performance and ensure proper ventilation. Key Features: Calculate required duct dimensions using CFM and FPM values. Supports both rectangular and circular duct sizing in inches. Calculate air flow rate accurately in CFM. Determine air velocity in FPM for system Ideal for HVAC engineers, designers, and installation technicians. Simple interface for fast calculations on-site or during design work. Duct Calculator is a reliable and practical tool for heating, ventilation, and air conditioning professionals involved in the design, installation, and construction of ventilation systems. in-app purchase included Lifetime to Remove Ads Privacy Policy : Terms and Condition : ## Duct Calculator.
