Measurement and terminology

Units and terms that appear across device documentation, and what each one describes.

Device documents reuse a small set of quantities. Reading a specification sheet correctly depends on separating the energy delivered, the area it is delivered over, and the time it is delivered in.

Terminology entries in this topic define each quantity and note the unit it is normally published in.
