Unit prefixing

A unit prefix is a specifier or mnemonic that is prepended to units of measurement to indicate a multiple or a fraction of a unit, such as "kilo" for thousand. When unit prefixing is enabled in Operations Dashboard, symbols of unit prefixes, such as "k" for "kilo", are used to abbreviate numbers. Like number formatting, this can simplify the information presented and make a number easier to interpret. The below indicator has unit prefixing enabled.

Indicator with unit prefixing enabled

Operations Dashboard performs unit prefixing using standard metric prefix symbols. These represent multiplication by powers of ten. For example, the prefix "kilo" can be added to "meter" to indicate multiplication by one thousand (i.e. one kilometer is equal to one thousand meters). Likewise, the prefix "milli" may be added to "second" to indicate division by one thousand (i.e. one millisecond is equal to one thousandth of a second). The following tables outline how symbol prefixes can be applied to both large and small numbers in a dashboard. The only standard symbols Operations Dashboard doesn't honor are h (hector), da (deca), d (deci), and c (centi).
