ABSTRACT
The unit meter is often too large when describing length scales in matter, in liquid or solid state: here it may be more convenient to use ÝA (for ÝAngstrøm), where we have 1 m = 1010 ÝA.
The obvious unit for measuring temperatures is K (Kelvin), but in plasma physics one often uses electron volts, eV, to be understood as the potential K that fulÀlls the relation PT = eK. We have 1 eV ≈ 1.1604×104 K, or 103 K ≈ 86.17× 10−3 eV.
