(Any unit of mass) times (any unit of speed) is a unit of linear momentum. Angular momentum would need radians.
In the SI (metric) system, it's kilogram meter per second kg.m.s-1 or Newton-second.

Linear momentum is conserved in a closed system when there are no external forces acting on it. This means that the total linear momentum of the system before an event is equal to the total linear momentum after the event.
The linear momentum of an object can be calculated by multiplying the mass of the object by its velocity. The formula for linear momentum is: momentum = mass x velocity.
Linear momentum can be converted to angular momentum through the principle of conservation of angular momentum. When an object with linear momentum moves in a curved path or rotates, its linear momentum can be transferred to create angular momentum. This conversion occurs when there is a change in the object's direction or speed of rotation.
The linear momentum component that does not contribute to angular momentum is the component that is parallel to the axis of rotation. Only the perpendicular component of linear momentum contributes to angular momentum.
The formula for linear momentum (p) is: [ p = m \cdot v ] where: p is the linear momentum, m is the mass of the object, and v is the velocity of the object.
