Calculus also featured frequently in the 1957–1963 [[Hergé's Adventures of Tintin|Belvision TV series]], as well as in other adaptations of the comics. The Belvision TV series is notable for depicting Calculus with perfect hearing.

Calculus' original French name was "Tournesol" which is the French term for [[sunflower]]. In the 1970s and 1980s, he starred in a series of cartoon television commercials for [[Fruit d'or]] products which included [[cooking oil]] and [[mayonnaise]] made from sunflower oil. Some of the ads would conclude with him floating up into the air to demonstrate how they kept a good healthy balance. Other characters from the books were also included.<ref>[http://www.dailymotion.com/video/xw5g3_1979-fruit-dor-professeur-tournesol "Fruit D'or,"] Daily Motion.</ref>

A pseudonym variation was used on an album by [[Stephen Duffy]] – see [[Stephen Duffy#Tin Tin|Tin Tin]] and "Dr. Calculus".
