# vectorMagnitude

*Command · Math - Vectors · Arma 3 v1.22*

## Description

Magnitude of a 3D vector.

> [!NOTE]
> **Since Arma 3 v2.14:** Since Arma 3 v2.14 any count of numbers is valid.
>
> Before Arma 3 v2.14, the argument had to be vector 3D, or Arma 3 v2.00 2D (With z coordinate defaulted to 0)

## Syntax

```sqf
vectorMagnitude vector
```

**Parameters:**

- `vector`: [Array](../topics/Array.md) of [Number](../topics/Number.md)s

**Returns:** [Number](../topics/Number.md)

## Examples

### Example 1

```sqf
_size = vectorMagnitude [0,3,4]; // returns 5
```

### Example 2

```sqf
_speed = vectorMagnitude velocity player;                // return velocity of player in m/s
_speed = (vectorMagnitude velocity player) * 3.6;        // return velocity of player in km/h
_speed = (vectorMagnitude velocity player) * 2.23694;    // return velocity of player in mph
```
