Prefix multiplication of unit selbri
Cf. te'ai. Used to construct selbri for units such as coulombs, which is pi'ai xampo snidu [ke'e] which is x1 is measured in Coulombs (Ampere-seconds) as x2 (li) etc. Since pi'ai is prefix, pi'ai mitre snidu grake [ke'e] is m s g, etc.; separate multipliers are not necessary.
