What does centesimally mean?
Centesimally is a formal mathematical adverb meaning in hundredths or according to units of one hundredth. It is used when a measurement or calculation is expressed with a degree of precision smaller than a whole unit, as in a scale marked centesimally. The word can also indicate multiplication by one hundred, depending on the context. Its sound suggests a more elaborate vocabulary than the simpler phrases “in hundredths” and “by hundredths,” but its actual usage is uncommon and largely technical. Centesimally derives from the Latin centesimus, meaning “hundredth,” ultimately from centum, “hundred.” Understanding the word is useful in mathematical, scientific, and historical contexts where fine gradations or exact fractional relationships matter.
