According to this answer, ARKit uses meters for measuring.
Is there any official source for this, somewhere within Apple's Documentation, for example? I've been searching for hours.

SceneKit’s world space corresponds to the meter defined in the International System of Units.
The same units are set for ARKit space and RealityKit space.
Watch ARKit WWDC 2017 video (time: 14:32).
