1910 January, “Multiplication of Decimals”, in The Practical Teacher, volume 30, number 7, page 414:
Similarly, in multiplying 0.6 by 0.03, the 6 deci-units have to be “centimated”—that is, divided into 100 equal parts, each part obtained being 6 “milli-units,” or .006; and then 3 such parts taken, giving 18 “milli-units,” or 0.018, for the result—a quantity less than 0.6.
2017, Lucy Grig, Popular Culture in the Ancient World, Cambridge University Press, page 144?:
Macrinus was also so harsh in his disciplining of the army (at whose hands he eventually met his death) that he supposedly coined the term ‘centimate’ as a lenient respite from his frequent decimations; and his brutal and degrading treatment of the army, no doubt a matter of popular concern, earned him derogatory taunts from the crowd in the Circus Maximus [...].
