The <henry (unit)> is the <SI> unit of <inductance>:
$$
1\,\mathrm H=1\,\frac{\mathrm{Wb}}{\mathrm A}
=1\,\frac{\mathrm{V\,s}}{\mathrm A}.
$$
A coil with <self-inductance> $1\,\mathrm H$ has <magnetic flux linkage> $1\,\mathrm{Wb}$ at <electric current> $1\,\mathrm A$. A rate of change of <electric current> $1\,\mathrm{A/s}$ produces induced <electromotive force> of magnitude $1\,\mathrm V$. The <weber (unit)> measures <magnetic flux> and <magnetic flux linkage>; the <henry (unit)> measures their ratio to <electric current>. https://openstax.org/books/university-physics-volume-2/pages/14-2-self-inductance-and-inductors[OpenStax University Physics 2, §14.2: the unit of self-inductance]{ref}.
