Scalars and vectors quantities can represent the same measure e.g.
Energy = -mu/r + mc, ; -mu/r is scalar energy and mcV is vector energy.

Scalar and vector quantities are both used to describe physical quantities in physics. The key similarity between them is that they both involve numerical values. However, vector quantities also have a direction associated with them, while scalar quantities do not.

scalar
A scalar is a magnitude that doesn't specify a direction. A vector is a magnitude where the direction is important and is specified.
The product of a vector and a scalar is a new vector whose magnitude is the product of the magnitude of the original vector and the scalar, and whose direction remains the same as the original vector if the scalar is positive or in the opposite direction if the scalar is negative.
Hours is a scalar quantity, as it only represents the magnitude of time elapsed and does not have a direction associated with it.
