What does mensuration mean?
Mensuration means the act or process of measuring, but the word is most often used in a technical mathematical sense. It refers to calculating the dimensions, area, or volume of a geometric figure when certain measurements or relationships are already known. In geometry education, the field is commonly divided into plane mensuration, involving two-dimensional figures, and solid mensuration, involving three-dimensional ones. Surveyors, architects, and engineers may also use the term when describing the systematic measurement of land, structures, or other physical objects. Outside these specialized contexts, measurement is the usual and more accessible word. Mensuration is valuable because it names both a general activity and a recognized body of mathematical method. Its Latin ancestry, through mensura, also connects it with related English words such as measure, measurable, and mensurable.
nounMensuration is the act or process of measuring. In mathematics, it specifically refers to calculating dimensions, areas, or volumes of geometric figures from given measurements.
- The mathematical determination of the dimensions, area, or volume of a geometric figure from given measurements.
- The act or process of measuring.
"Careful mensuration of the irregular plot revealed that the boundary was longer than the survey map indicated."
"The mensuration of the vessel required estimates of its length, width, and depth."
"The course introduces students to mensuration formulae for regular solids."
The plural is uncommon because the process or field is usually referred to in the singular.
"The two mensurations differed slightly because they were made with different instruments."
The Latin root mensura means “measure,” so mensuration literally names the art of determining a figure's dimensions.

Where does mensuration come from?
Mensuration entered English during the late Middle English period from Latin mensurationem, a noun meaning “a measuring” or “measurement.” The Latin term was derived from mensurare, “to measure,” which was related to mensura, “measure” or “dimension.” Ultimately, these forms trace to mensus, the past participle of metiri, “to measure.”
How mensuration is actually used
Mensuration is chiefly formal and technical. It is encountered especially in geometry, surveying, and related practical mathematics, while everyday speakers normally use measurement.
