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 of the fact that coordinates in the Nether are $1/8$ the number they are in the Overworld (or $1/3$ in the Legacy Console Edition). 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 players have outposts in other biomes, they travel there via minecart or by walking. However, by using math, 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 Overworld. For example, to travel 800 blocks in the Overworld, you would only need to travel 100 blocks in the Nether.

Once you've made two nether portals in the Nether connecting to two different places in the Overworld, you can make a minecart railway or a boat-way made of ice/blue ice to get from one to another, for even quicker travel.

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).

You'll need to know how coordinates work.

Easiest and cheapest method
The most straight-forward way to connect two Overworld locations for faster travel via the Nether is as follows:

1. Find the coordinates of one of the two places in the Overworld you want to connect, then divide the X and Z values by 8 or by 3. Note these divided values, along with the unchanged Y value.

2. Travel to the other location in the Overworld you wish to connect, and build a Nether portal there.

3. Go through the first portal, bringing materials to build and light a second one, and head to those divided coordinates in the Nether. Try to place yourself at about the same Y coordinate (elevation), then make a second portal. You should come out at about the location you wanted to go.

Example
For 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 and wish to connect the two. Divide the X and Z of the village coordinates by 8, to get roughly X = 132 and Z = -98. Then, make a Nether portal at spawn, go through and travel to X = 132 and Z = -98 in the Nether, and up to Y=78. Make your Nether portal here, and when you go through into the Overworld, you should come out at or near the village.

More precise method
The above method does not let you choose exactly where your second portal appears in the Overworld. This method allows you to do so, but is more expensive as it requires you build three portals:

1. Build and light one Nether portal, but do NOT go through it.

2. Divide the X and Z coordinates of this portal as above, and note them, along with the Y.

3. Travel to the other Overworld place and build a second portal there.

4. Go through the second portal, bringing enough materials to build and light a third one, and head to the divided coordinates in the Nether.

5. Place the third portal there and go through it.

You should come out the first Nether portal you made.

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 appear closer to 7 times or 9 times the Nether coordinates.
