the units of mass gm and kg in CGS and SI system ,units of distance-m and km are some units which describe scalar quantity.
Units such as kilograms, seconds, and degrees Celsius can only describe scalar quantities. These units represent values that have magnitude but no direction, unlike vector quantities which require both magnitude and direction for complete description.
grams and seconds
Units such as meters, seconds, kilograms, and kelvin are examples of units that can only describe scalar quantities. These units do not have a direction associated with them and only quantify the magnitude of a physical quantity.
Vector quantities have both magnitude and direction, so they are expressed in units such as meters per second (velocity) or newtons (force). Scalar quantities only have magnitude and are represented by units such as meters (distance) or kilograms (mass).
Physical quantities can be broadly categorized as scalar or vector quantities. Scalar quantities have only magnitude, like mass or temperature, while vector quantities have both magnitude and direction, like velocity or force. Other types of physical quantities include derived quantities (obtained from combinations of base quantities) and dimensionless quantities (without units).
Yes, scalar quantities can be added, as long as they are the same dimension and you keep units straight. For example you cannot add cubic meters to square meters. But (especially in the imperial system) pounds and ounces, or feet and inches are added, and displayed in that fashion. Minutes and seconds is another.
Scalar - a variable quantity that cannot be resolved into components. Most of the physical quantities encountered in physics are either scalar or vector quantities. A scalar quantity is defined as a quantity that has magnitude only. Typical examples of scalar quantities are time, speed, temperature, and volume. A scalar quantity or parameter has no directional component, only magnitude. For example, the units for time represent an amount of time only and tell nothing of direction. Vector - a variable quantity that can be resolved into components. A vectorquantity is defined as a quantity that has both magnitude and direction. To work with vector quantities, one must know the method for representing these quantities. Magnitude, or "size" of a vector, is also referred to as the vector's "displacement." It can be thought of as the scalar portion of the vector and is represented by the length of the vector. By definition, a vector has both magnitude and direction. Direction indicates how the vector is oriented relative to some reference axis.

Grams and seconds.
Vector quantities have both magnitude and direction, so they are expressed in units such as meters per second (velocity) or newtons (force). Scalar quantities only have magnitude and are represented by units such as meters (distance) or kilograms (mass).
Miles per hour and seconds are units of measurement of speed and time respectively, which are scalar quantities.
speed and direction
Vector quantities can be described using units such as meters (m), newtons (N), and kilograms (kg) for displacement, force, and mass, respectively. Additionally, vector quantities like velocity can be measured in meters per second (m/s) and acceleration in meters per second squared (m/s^2).

Units that are used for measures in which the direction is relevant. Example are displacement, velocity, acceleration, force.
Scalar quantities are equal if they have the same magnitude: if the numbers describing them, including units, are the same. The reason for specifying "including units" is that 1 inch is not equal to 1 kilometre even though the numbers describing the two lengths are equal. Vectors, such as velocity or acceleration or force, are equal if their magnitudes as well as their direction are the same.
