Many times, players may have to walk or ride a minecart thousands of blocks in order to get from one place to another. However, the Nether can be used as a much quicker travel, because coordinates in the Nether are $1/8$ the number they are in the Overworld. This means that the distance traveled in the Nether, that would be traveled in the Overworld, is 8 times as short as it would be if it were to be traveled in the Overworld.

Introduction
Often, when playeds have outposts in other biomes, they travel there via minecart or by walking. However, by using maths, a much quicker alternative is to get there via a nether portal! This works because one block in the nether is equal to eight blocks in the over world. For example, to travel 800 blocks in the Overworld, you would only need to travel 100 blocks in the nether.

Materials
You will need the following materials:


 * 10 obsidian (or 14 if you want to fill in the corners with obsidian)
 * A flint and steel, fire charge, or anything that can set the inside of the nether portal on fire (flint and steel is the easiest)
 * Basic materials to help you survive the Nether (see "Tutorials/Nether survival")

Coordinate Facts
The following facts will help greatly when working with traveling long distances in specific directions. Coordinates and directions can be found on the debug screen, which can be opened by pressing F3.

X- Increases east, decreases west.

Y- Increases by height, decreases by depth.

Z- Increases south, decreases north.

This means that a negative X value is west of the x-coordinate 0, and a positive X value is east of the x-coordinate 0. Likewise, a negative Z value is north of the z-coordinate 0, and a positive Z value is south of the z-coordinate 0.

Steps
To use the Nether to travel to far-away locations in the Overworld, follow these steps:

1. You will need a nether portal. If you don't have one, make one.

2. Find your desired location you want to travel to in the Overworld.

3. Note the coordinates of the area, then divide the X and Z values by 8 or by 3. You can ignore the Y value.

4. Go through your portal & head to those divided coordinates in the Nether this time. Try to place yourself at about the same elevation, then make your portal. You should come out about where you were previously.

5. Another option is to make your Nether portal in your desired location in the Overworld first.

Example
For an example, say that your spawn is at X = 92, Y = 66, and Z = 45. You have found a village at coordinates X = 1054, Y = 78, and Z = -786. Divide the X and Z of the village coordinates by 8, to get roughly X = 132 and Z = -98. Then, you would make a Nether portal at spawn, and travel to X = 132 and Z = -98 in the Nether. You would then make your Nether portal here, and when you would have gone through into the Overworld, you should have come out at or near the village.

Comparing Coordinates
Compare the following 2 pictures. The first one shows coordinates in the Overworld at a Nether portal. The second one shows the corresponding coordinates in the Nether. You will notice that the Overworld X and Z coordinates are about 8 times the coordinates in the Nether, although sometimes they may closer to 7 times or 9 times the Nether coordinates.
