From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]:

Ohm  \Ohm\,  n.  [So  called  from  the  German  electrician,  G.S.  Ohm.]
(Elec.)
The  standard  unit  in  the  measure  of  electrical  resistance,
being  the  resistance  of  a  circuit  in  which  a  potential
difference  of  one  volt  produces  a  current  of  one  amp['e]re.
As  defined  by  the  International  Electrical  Congress  in  1893,
and  by  United  States  Statute,  it  is  a  resistance
substantially  equal  to  10^{9}  units  of  resistance  of  the
C.G.S.  system  of  electro-magnetic  units,  and  is  represented
by  the  resistance  offered  to  an  unvarying  electric  current  by
a  column  of  mercury  at  the  temperature  of  melting  ice  14.4521
grams  in  mass,  of  a  constant  cross-sectional  area,  and  of  the
length  of  106.3  centimeters.  As  thus  defined  it  is  called  the
{international  ohm}.

{Ohm's  law}  (Elec.),  the  statement  of  the  fact  that  the
strength  or  intensity  of  an  electrical  current  is  directly
proportional  to  the  electro-motive  force,  and  inversely
proportional  to  the  resistance  of  the  circuit.

From  WordNet  r  1.6  [wn]:

ohm
n  1:  a  unit  of  electrical  resistance  equal  to  the  resistance
between  two  points  on  a  conductor  when  a  potential
difference  of  one  volt  between  them  produces  a  current
of  one  ampere
2:  (1787-1854)  the  German  physicist  who  formulated  Ohm's  Law
[syn:  {Ohm},  {Georg  Simon  Ohm}]

From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]:

Ohm

The  {MKS}  unit  of  electrical  resistance.  One  Ohm  is
the  resistance  of  a  conductor  across  which  a  {potential
difference}  of  one  {Volt}  produces  a  {current}  of  one
{Ampere}.
