Based on Steinmetz experiments, "Steinmetz's formula" defines the approximate heat energy due to magnetic hysteresis released, per cycle per unit area of magnetic material.{{efn|<math>W_h=\eta\Beta^{k}_{max}</math>, where η is hysteresis coefficient, β<sub>max</sub> is maximum flux density and k is an empirical exponent.}}<ref name="Knowlton1949-1">{{harvnb|Knowlton|1949|pp=49 (§2.67), 323 (§4.280)}}</ref> [[Induction motor#Steinmetz equivalent circuit|Steinmetz equivalent circuit]] theory is still widely used for the design and testing of induction motors.<ref name="Knowlton1949-2">{{harvnb|Knowlton|1949|p=711 (§7.207)}}</ref><ref name="Steinmetz1897">{{harvnb|Steinmetz|Berg|1897|loc=|}}</ref>
 
One of the highest technical awards given by the [[Institute of Electrical and Electronics Engineers]], for major contributions to [[standardization]] within the field of electrical and electronics engineering, is named in his honor as the [[IEEE Charles Proteus Steinmetz Award]]. Other awards include the [[Franklin Institute#Awards|Certificate of Merit]] of [[Franklin Institute]], 1908; the [[Elliott Cresson Medal]], 1913; and the [[Cedergren Medal]], 1914.

Steinmetz Hall, which houses the Union College computer center, is named after him.
 
Steinmetz was portrayed in 1959 by the actor [[Rod Steiger]] in the [[CBS television]] [[anthology series]], ''[[The Joseph Cotten Show]]''. The episode focused on his socialist activities in Germany.

Novelist [[John Ball (author)|John Ball]] grew up in Steinmetz's house. His parents were graduate students paid by General Electric to live with and take care of the man Ball called "Uncle Steinie". Ball used to tell his Steinmetz stories at the Southern California Mystery Writers Association meetings.{{citation needed|date=July 2014}}
 
Steinmetz is a major character in the novel ''Electric City'' by [[Elizabeth Rosner]]. In this epic story of technology, Rosner connects Steinmetz's early ethos as a socialist with his humanitarian vision of a better society based on technological progress: "The political arena that had summoned him in his youth, Socialist views that sent him into exile all those years earlier, further contributed to a seemingly endless hunger for change".<ref>''Electric City'', Berkeley: Counterpoint, 2014, p. 53.</ref>
