In geometry, the diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle.

In the industrial or industry context, diameter refers to the distance across the widest part of a circular object or the measurement of a straight line that passes through the center of a circular object and touches its outer edge.

Examples of diameter in the industrial context include:

• The diameter of a drill bit used for drilling holes
• The diameter of a pipe for transporting liquids or gases
• The diameter of a wheel used in material handling equipment
• The diameter of a gear used in machinery.
