Mass-to-charge ratio used as its unit in the field of mass spectrometry. Some fields use the charge-to-mass ratio ("Q"/"m") instead, which is the multiplicative inverse of the mass-to-charge ratio. The 2014 CODATA recommended value for an electron is = . When charged particles move in electric and magnetic fields the following two laws apply: where F is the force applied to the ion, "m" is the mass of the particle, a is the acceleration, "Q" is the electric charge, E is the electric field, and v × B is the cross product of the ion's velocity and the magnetic flux density.

Jane (given name) Jane (given name) Jane is a feminine given name. It is the English form of the Old French name Jehanne, which was an old feminine form of the male name Johannes or Ioannes (also the source of the English name John), a Latin form of the Greek name (Iōannēs), which is derived from the Hebrew name יוֹחָנָן (Yochanan), a short form of the name יְהוֹחָנָן (Yehochanan), meaning "Yahweh is merciful".
