The game of minecraft is seriously fun to play. When you have played the game long enough to be at a stage where you are building nether portals, that is when you can use this quick calculator. 

It helps you find where to build your return gate so that it can be connected as a pair between the nether and the overworld. 

Nether portals make traveling across the overworld much faster than usual. However, if you are playing in a world with other players of your kind who build gates, it’s not really uncommon to materialize in an unexpected location when stepping through a nether portal.

You should use this calculator to see where you should put your nether portals in Minecraft. The ideal calculation behind the nether portal is relatively simple. However, every so often we all do need a little help here and there while computing the perfect place to put our nether portal. 

With this super easy to use and handy little chrome extension available at no cost at all you can have the calculator right at your fingertips! 

All you need to do is just input the X/Y/Z of your Overworld coordinates to find the correct location for the linking Portal in the Nether. In fact, you can even do it the other way around.
