The Imperial units of measure are a combination of British and Roman units, that have been standardized over time. Go to the attached link titled "English Units", to learn a little more about various Imperial and other measures.
Imperial system
Though there is no exact Imperial equivalent to the metre the SI units of measurement are replacing the Imperial units as they are more convenient and self consistent.
The SI unit is a Newton while an Imperial unit was a pound-force (not a pound).
Momentum (P) is the product of mass (m) and velocity (v). P = m X v It's easy to get confused by combining metric units (grams) with imperial units (miles per second). Converting all the units to one system first will simplify calculations.
Linear momentum of an object is its mass times its velocity. Since momentum does not have a unit name of its own its units are whatever you use for mass & velocity. The SI units would be Kg-M/S . The cgs units would be gm-cm/S , and the English units would be Slug-Ft/S . It can also be expressed in terms of force units. SI: Newton-Sec. , Cgs :dyne-Sec, English: Pound-Sec.
A measure of length or distance expressed in Imperial units.
"Motion" can be expressed in units of speed. Or it might refer to momentum - in which case you would use any unit of mass x velocity.
It is expressed in whichever system you use for mass. Most people use Metric and some use English. English would be the ounce and Metric would be the gram.The SI unit of momentum (P) is Newtown*second (N*s) and also kilograms* meters per second (kg*m/s). P equals mass (in kilograms) multiplied by velocity (in meters per second).

Though there is no exact Imperial equivalent to the metre the SI units of measurement are replacing the Imperial units as they are more convenient and self consistent.
Momentum is defined as mass times velocity, and it requires units of mass times units of velocity. The SI unit is kilograms x meters / second. There is no special name for this combination of units.
Because of their association with the Brittish Empire.
