The inductance of an electric circuit is one henry when an electric current that is changing at one ampere (A) per second (s) results in an electromotive force of one volt (V) across the inductor: V(t) = L ^dI⁄_dt, where V(t) denotes the resulting voltage across the circuit, I(t) is the current through the circuit, and L is the inductance of the circuit.

The henry is a derived unit based on four of the seven base units of the International System of Units: kilogram (kg), meter (m), second (s), and ampere (A). Expressed in combinations of SI units, the henry is: H = ^kg∙m2⁄_s²∙A² = ^N∙m⁄_A² = ^kg∙m2⁄_C² = ^J⁄_A² = ^T∙m2⁄_A = ^Wb⁄_A = ^V∙s⁄_A = ^s2⁄_F = ^Ω⁄_Hz = Ω∙s. Where: H = henry, kg = kilogram, m = meter, s = second, A = ampere, N = newton, C = coulomb, J = joule, T = tesla, Wb = weber, V = volt, F = farad, Ω = ohm, Hz = hertz.

Mednarodni sistem enot (SI) določa, da napiše simbol enote, imenovane za osebo z začetno kapitalsko črko, medtem ko ime ni izkoriščeno v stavčnem besedilu, razen kadar bi bila vsaka beseda v tem položaju izkoriščena, na primer na AT začetek stavka ali v materialu z naslovom. Nacionalni inštitut za standarde in tehnologijo ZDA priporoča uporabnikom, ki pišejo v angleščini, da uporabljajo množino kot Henries.

The inductance of a coil depends on its size, the number of turns, and the permeability of the material within and surrounding the coil. Formulas can be used to calculate the inductance of many common arrangements of conductors, such as parallel wires, or a solenoid. A small air-core coil used for broadcast AM radio tuning might have an inductance of a few tens of microhenries (μH). A large motor winding with many turns around an iron core may have an inductance of hundreds of henries. The physical size of an inductance is also related to its current carrying and voltage withstand ratings.
