(definition)

**Definition:**
The distance between two points measured along axes at right angles. In a plane with p_{1} at (x_{1}, y_{1}) and p_{2} at (x_{2}, y_{2}), it is |x_{1} - x_{2}| + |y_{1} - y_{2}|.

**Generalization** (I am a kind of ...)

*L _{m} distance*.

**See also**
*Euclidean distance*, *Hamming distance*.

*Note:
This is easily generalized to higher dimensions. Manhattan distance is often used in integrated circuits where wires only run parallel to the X or Y axis. See links at L_{m} distance for more detail. *

Also known as *rectilinear* distance, Minkowski's L_{1} distance, taxi cab metric, or city block distance.

* Hamming distance can be seen as Manhattan distance between bit vectors.*
