'''Engineering notation''' or '''engineering form''' (also '''technical notation''') is a version of [[scientific notation]] in which the exponent of ten is always selected to be divisible by three to match the common metric prefixes, i.e. scientific notation that aligns with powers of a thousand, for example, 531×10<sup>3</sup> instead of 5.31×10<sup>5</sup> (but on calculator displays written without the ×10 to save space). As an alternative to writing powers of 10, [[SI prefix]]es can be used,<ref name="Gordon_1969"/> which also usually provide steps of a factor of a thousand.<ref group="nb" name="NB_Cubic"/>
On most calculators, engineering notation is called "ENG" mode as scientific notation is denoted SCI.
