New Hampshire does not have a single longitude. It is a state with a range of longitudes.

Here's why:

* States are not points: They are areas with borders that stretch across both latitude and longitude.

* Longitude lines run north-south: The furthest west point in New Hampshire will have a different longitude than the furthest east point.

Instead of a single longitude, New Hampshire's range of longitudes is roughly:

* Westernmost: 71.9° West

* Easternmost: 70.6° West
