Room Volume Calculator for HVAC (m³ and ft³)
The Room Volume Calculator helps HVAC engineers, designers, and students calculate the volume of a room in cubic meters (m³) and cubic feet (ft³). Room volume is a key input for ventilation, ACH, cooling load, and heating load calculations.
Room Volume Calculator
Room Volume Formula
Room Volume (m³) = Length × Width × Height
This formula applies to rectangular rooms and is commonly used in HVAC design and ventilation calculations.
Example Room Volume Calculation
- Length = 6 m
- Width = 5 m
- Height = 3 m
- Room Volume = 90 m³
Where Room Volume Is Used in HVAC
- Air Changes per Hour (ACH) calculation
- Ventilation airflow estimation
- Cooling load calculation
- Heating load calculation
