  2. Foot–pound–second system of units - Wikipedia

    en.wikipedia.org/wiki/Footpoundsecond...

    The electrostatic and electromagnetic systems are derived from units of length and force, mainly. As such, these are ready extensions of any system of containing length, mass, time. Stephen Dresner [7] gives the derived electrostatic and electromagnetic units in both the footpoundsecond and foot–slug–second systems. In practice, these ...

  3. Slug (unit) - Wikipedia

    en.wikipedia.org/wiki/Slug_(unit)

    Systems of measure either define mass and derive a force unit or define a base force and derive a mass unit [1] (cf. poundal, a derived unit of force in a mass-based system). A slug is defined as a mass that is accelerated by 1 ft/s 2 when a net force of one pound (lbf) is exerted on it.

  4. Poundal - Wikipedia

    en.wikipedia.org/wiki/Poundal

    For example, a force of 1200 poundals is required to accelerate a person of 150 pounds mass at 8 feet per second squared: = The poundal-as-force, pound-as-mass system is contrasted with an alternative system in which pounds are used as force (pounds-force), and instead, the mass unit is rescaled by a factor of roughly 32.

  5. Mass flow rate - Wikipedia

    en.wikipedia.org/wiki/Mass_flow_rate

    Mass flow rate is defined by the limit [3] [4] ˙ = =, i.e., the flow of mass through a surface per time .. The overdot on ˙ is Newton's notation for a time derivative.Since mass is a scalar quantity, the mass flow rate (the time derivative of mass) is also a scalar quantity.

  6. Foot-poundal - Wikipedia

    en.wikipedia.org/wiki/Foot-poundal

    The foot-poundal (symbol: ft-pdl) is a unit of energy, introduced in 1879, that is part of the Absolute English system of units, which itself is a coherent subsystem of the footpoundsecond system. [1] The foot-poundal is equal to 1/32.174049 that of the more commonly used foot-pound force.

  9. Pound (force) - Wikipedia

    en.wikipedia.org/wiki/Pound_(force)

    The pound of force or pound-force (symbol: lbf, [1] sometimes lb f, [2]) is a unit of force used in some systems of measurement, including English Engineering units [a] and the footpoundsecond system. [3] Pound-force should not be confused with pound-mass (lb), often simply called "pound", which is a unit of mass; nor should these be ...
