# Vector Length Calculator

The Vector Magnitude Calculator is a easy-to-use tool that will help you calculate the magnitude of a vector by simply entering its X, Y, and Z components. For a more advanced calculation, enter two vectors in (X,Y,Z) format to find their dot product.

Whether you need to determine vector magnitude or calculate the dot product of two vectors, this calculator provides quick and accurate results. Just input the necessary values, and the calculator will handle the rest, giving you the vector magnitude or dot product in the result field.

In both mathematicians or physicists calculating vector magnitudes or dot products is straightforward, but this Vector Magnitude Calculator makes this easy. It offers both basic and advanced calculators for different needs.

### What Is Vector Magnitude

The magnitude of a vector measures its length. In three-dimensional space, a vector is defined by its components along the X, Y, and Z axes. The magnitude provides a single scalar value representing the distance from the origin to the point defined by the vector.

### Vector Magnitude Formula

To calculate the magnitude of a vector with components X, Y, and Z, use this formula:

$\text{Magnitude} = \sqrt{X^2 + Y^2 + Z^2}$

### Dot Product Formula

The dot product of two vectors

$A = (A_x, A_y, A_z)$

$B = (B_x, B_y, B_z)$

is calculated as:

$\text{Dot Product} = A_x \times B_x + A_y \times B_y + A_z \times B_z$

### How to Use the Calculator

The Vector Magnitude Calculator has two modes: Basic and Advanced.

**1. Basic Calculator:**

- Enter the X, Y, and Z components of your vector.
- Click “Calculate” to compute the magnitude.
- View the result in the “Vector Magnitude” field.

**2. Advanced Calculator:**

- Enter the components of Vector A in the format X, Y, Z.
- Enter the components of Vector B in the same format.
- Click “Calculate” to compute the dot product.
- View the result in the “Vector Dot Product” field.

### Calculation Examples

**1. Basic Calculation Example:**

Suppose you have a vector with components

$X = 3$

$Y = 4$

, and

$Z = 5$

.

- Enter 3 in the X field, 4 in the Y field, and 5 in the Z field.
- Click “Calculate”.
- The magnitude is: $\text{Magnitude} = \sqrt{3^2 + 4^2 + 5^2} = \sqrt{9 + 16 + 25} = \sqrt{50} \approx 7.07$
