The SI unit for torque is the newton-meter (N-m). The SI unit for angular momentum is kilogram square meter per second (kg.m^2/s).
Angular momentum is a vector quantity and therefore has dimensions of mass multiplied by length squared divided by time. In SI units, the dimension of angular momentum is kg * m^2/s.
case 1 is mass (m) on weightless length (r) of string at constant velocity (v), so angular momentum L = r * (m * v), SI units are n.m.s. or kg.m^2.s^-1 . case 2 is mass(m) rotating around an axis inside its own mass ie solid sphere rotating about its fixed symmetry axis, angular momentum L = I * w, where I is the mass moment of inertia of the sphere about its fixed symettry axis, and w is the rotation in radians per second, units are kg.m^2 for I, and rad / sec for w
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.
Momentum is the product of mass times velocity, so in SI units, the units are kilograms x meters / second. There is no special name for this unit.
The formula for momentum is (mass)*(velocity), so the SI units would bekg m sec-1 or kg-m/sec
Angular momentum is a vector quantity and therefore has dimensions of mass multiplied by length squared divided by time. In SI units, the dimension of angular momentum is kg * m^2/s.
Angular momentum is defined as the cross product of a distance (from the axis of rotation) and a momentum, so you have to use units accordingly. In the SI, that would be meters x kilograms x meters / second, which you can simplify to meters squared x kilograms / second. This is equivalent to joules x seconds.

Momentum is mass * velocity. Its units, in the SI system are kilogram metre per second

The rotating object's moment of inertia. Similar to Newton's Second Law, commonly quoted as "force = mass x acceleration", there is an equivalent law for rotational movement: "torque = moment of inertia x angular acceleration". The moment of inertia depends on the rotating object's mass and its exact shape - you can even have a different moment of inertia for the same shape, if the axis of rotation is changed. If you use SI units, and radians for angles (and therefore radians/second2 for angular acceleration), no further constants of proportionality are required.
Linear momentum is (mass)*(velocity)[a vector mv], so the SI unit would be kg*m/s, angular momentum is the sum of all resultant vectors of r x mv for each point on a spinning object, and would have units kg*m2/s
You must convert the mass from pounds to kilograms, time from seconds to seconds, and distance from feet to meters. Only then can you use the formula for momentum (momentum = mass * velocity) to calculate momentum in SI units (kg*m/s).
Radian is the unit for angular displacement is SI system of units.
Momentum is a vector quantity, calculated as the product of an object's mass and velocity. Its SI unit is kilogram meters per second (kg m/s), which represents the combination of mass (kg) and velocity (m/s) in defining momentum. Momentum does not have a separate designated unit name because it is derived from fundamental SI units.
