What unit is air velocity measured in?
Air velocity is typically measured in units of meters per second (m/s) or feet per minute (ft/min).
How many cubic feet of air makes 1 liter of air?
1 liter of air is equivalent to approximately 0.0353 cubic feet of air.
The measurement of how much air is moved through an air-conditioning unit?
The measurement of how much air is moved through an air-conditioning unit is typically referred to as airflow. It is commonly measured in cubic feet per minute (CFM) and is important for ensuring proper ventilation and cooling in a space. Monitoring airflow helps maintain the efficiency and performance of the air-conditioning system.
How many cubic feet of air does it require for a furnace to burn 1 cubic foot of natural gas?

What is air movement measured in?
Air movement is measured using anemometers. Air speeds inside a building tend to be relatively low, usually less than 1 m/s. This means the anemometers used for this purpose have to be much more sensitive than those used in weather stations measuring wind. There are two main types of internal anemometer, those based on a small propeller and those based on the cooling of a hot metal wire exposed to the air. Propeller based systems tend to be a little less sensitive at very low air speeds, however bearing technology and ultra-lightweight materials are increasingly proving this to be incorrect. Below is a picture of a anemometer.
