## Vector Length Formula

The following formula is used to calculate a vector length.

|u| = √(x₁² + y₁² + z₁²)

- Where u is the vector length
- x is the x coordinate
- y is the y coordinate
- z is the z coordinate

## Vector Length Definition

A vector length is equivalent to a vector magnitude and is equal to the square root of the sum of the squares of each vector unit.

## How to calculate a vector length?

How to calculate a vector length

**First, determine the vector coordinate points**This will be x, y, and possibly z if the vector is in the 3-D plane.

**Calculate the magnitude**Calculate the vector length using the formula above.

## FAQ

**What is vector length?**

A vector length is another way of saying a vector magnitude. It’s a measure of distant from the origin 0,0,0 to the coordinate points of the vector.
