# How do you calculate air flow in a room?

In English, they moved from CFM to cubic feet per hour (CFH). Then we calculated the volume of the piece by multiplying the height of the piece with the width for the length. Then we shared CFH with the volume of the piece.Then we calculated the volume of the room by multiplying the height of the room with the width by the length. Then we shared the CFH with the volume of the room.
