Tile

A tile is the smallest piece of the world-map. The whole factorio world is made out of them.

Tiles are both: a unit to measure areas and distances.

A Chunk has 32x32 tiles. The chunk is the next biggest unit for area/distance.

Examples

• Area covered by radar: 100 tiles Diameter (100 tiles in each direction)
• Speed of basic belt: about 1.8 tiles/sec.
• it take about 2 minutes and 47 seconds to run 1000 tiles without speed up. Which means that the character is a very healthy man/woman.

Real size of tiles

Tile is generally assumed to be 1 square meter in size (like Minecraft).

Length or area?

If you want to make clear if you speak from tile as length or tile as area, please use something like "tiles length", "square tiles", "tile^2", or similar writing, but in most cases it should be clear.
