x_{1} is measures equal to/is an elementary negative electric charge [-e; negative of the charge of the proton, id est the charge of the electron] in electric charge, under signum convention x_{2} (default: proton charge is -1 times this unit).

The number is negative. Approximately equal to: -1.602176565(35)×10^{-19} coulombs. Attention: the standard English unit is positive (opposite of this Lojbanic version). See also ".ocnerta", "dikca", "ku'arkydicka'u".
