In mathematics, the term magnitude is greatly used in vectors.

The magnitude of a vector is the length of the vector and is denoted as ∥a∥.

The magnitude of a number is also called its absolute value.

**Formula to calculate magnitude.**

**Example: **

Suppose vector PQ’s coordinates is (2,3), (4,5). Calculate the vector’ magnitude.

Therefore, the vector’s magnitude is 2.83 units.
