Room Volume Calculator
Calculate room volume in cubic feet from length, width and ceiling height, with CFM, ACH and BTU planning estimates.
Room volume in cubic feet
Room-volume intent in English search is usually practical: find cubic feet for HVAC, ventilation, storage or acoustic planning. CFM and BTU outputs should stay preliminary.
Use feet for all three dimensions to get cubic feet.
ACH is air changes per hour; 60 converts hours to minutes.
