FTPM = Feet Per Minute C = Circumference of Roll in Feet or Length of Felt in Feet RPM = (1/C)*FTPM To get the Circumference of the roll take the roll diameter (usually in inches) multiply by Pi 3.142 and divide that answer by 12 to get the answer into feet. Note: Meter per minute is a metric unit of speed. Velocity is speed in the context of direction. Please enter the speed and distance values to calculate the travel time in hours, minutes and seconds. Foot per minute is an imperial or United States customary unit of speed. Air velocity (distance traveled per unit of time) is usually expressed in Linear Feet per Minute (LFM). This online calculator helps you to calculate either of the three parameters namely, the air flow in FPM (Feet per Minute), CFM and the area in square feet. The symbol for feet per minute is ft/m. Say you were walking backward again; your velocity is negative 2 m/s, although your speed is still positive. Facebook Google+ Twitter. By multiplying air velocity by the cross section area of a duct, you can determine the air volume flowing past a point in the duct per unit of time. Walk forward or backward at 2 meters per second, and your speed is just that: 2 m/s. Time format HH:MM:SS. Volume flow is usually measured in Cubic Feet per Minute (CFM). Feet per minute is a unit of Speed or Velocity in both US Customary Units as well as the Imperial System. From: to 100 by: with precision: « ‹› » ∇ O? D = Diameter in Inches Circumference in Feet = (D*3.142)/12 This online calculator tool can be a great help for calculating time basing on such physical concepts as speed and distance. By knowing any two parameters we can calculate the remaining parameter using this cubic feet per minute conversion calculator. 00:00:00. Calculate Clear.

Select a Conversion. Meter Per Minute (m/min) is a unit of Speed used in Metric system. How many feet per minute in 4 meters per minute: If v m/min = 4 then v ft/min = 3.2808399 × 4 = 13.1233596 ft/min.

Calculator Use. 1 meter per minute (m/min) = 3.2808399 foot per minute (ft/min). It measures the number of feet traveled in a minute. It is calculated in either Cubic Feet per Minute (CFM) or Feet per Minute (FPM). Speed is the rate of change in position of an object, regardless of direction of travel. Speed. Foot Per Minute (ft/min) is a unit of Speed used in Standard system.
