'''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, 531×10³ instead of 5.31×10⁵ (but on calculator displays written withoutin the[[E notation]] - with "E" instead of "×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.
