arc length

Distance along curve

Arc length is the distance along a curved line between two points, measured by tracing the curve rather than cutting straight across.

In geometry, arc length typically refers to a portion of a circle's circumference: The arc length of a quarter circle equals one-fourth the circumference.

The concept extends to any curve in mathematics and physics.
