### Which are the scalar quantities?

A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a scalar; force is usually indicated as a vector (magnitude in Newton, but the direction is also relevant). A scalar quantity is a non-vector quantity. In a vector quantity, direction is relevant. In a scalar quantity, it is not. For example, mass (measured in kg.) is a…

### Can a scalar quantity be made into a vector quantity by adding a direction to its magnitude why or why not?

Yes this happens in case of area. Usually area is a scalar quantity. But we provide the direction of course perpendicular to its plane area we make it as a vector. Same way though electric current is not a vector it is sensed as vector as we put along with length of conductor. I is scalar but Idl is vector.
