x_{1} is the elementary unit (quantum) of angular momentum/half of Planck's reduced constant [id est: hbar/2 = h/(4 pi)] expressed in units x_{2} (default: unitless/dimensionless and so that it is equal to 1) in paradigm/system/metaphysics/universe x_{3} (default: this, our actual, physical universe)

This unit is not equal to hbar itself, but half thereof; it is equal to the absolute value/magnitude of magnetic quantum number of an electron. In our world and in SI units, this quantity is approximately equal to: 5.27285863 × 10^{-35 (m}. See also gravnutnoia, tcelerita, boltsemaku, avgadro, ocnerta, paulcna.
