Diametre vs. Diameter — What's the Difference?

Alternative form of diameter

In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle.

A straight line segment passing through the center of a figure, especially of a circle or sphere, and terminating at the periphery.

The length of such a segment.

Thickness or width.

A unit of magnification equal to the number of times an object's linear dimensions is increased by the magnifying apparatus.

(geometry) Any straight line between two points on the circumference of a circle that passes through the centre/center of the circle.

(geometry) The length of such a line.

(geometry) The maximum distance between any two points in a metric space

(graph theory) The maximum eccentricity over all vertices in a graph.

Any right line passing through the center of a figure or body, as a circle, conic section, sphere, cube, etc., and terminated by the opposite boundaries; a straight line which bisects a system of parallel chords drawn in a curve.

The length of a straight line through the center of an object from side to side; width; thickness; as, the diameter of a tree or rock.

The distance through the lower part of the shaft of a column, used as a standard measure for all parts of the order. See Module.

The length of a straight line passing through the center of a circle and connecting two points on the circumference

A straight line connecting the center of a circle with two points on its perimeter (or the center of a sphere with two points on its surface)
