Detailed Solution

The SI unit of weight is based on the concept of force. Weight is the force exerted on an object due to gravity. It is defined by the equation:

Weight (W) = m × g

Where:

m is the mass of the object, which is measured in kilograms (kg).
g is the acceleration due to gravity, with an SI unit of meters per second squared (m/s²).

The SI unit of weight is therefore derived as kg × m/s², which is equivalent to a Newton (N).

Thus, the SI unit of weight is Newton (N), which is the unit of force in the International System of Units (SI).

In conclusion, the SI unit of weight is the Newton (N), symbolizing the force experienced by an object due to gravity.
