With divisor/multiplier steps of 10 between units, in contrast with the steps of 2 and its powers for binary and its compounds, of 12 for duodecimal, of 16 for hexadecimal, of 20 for vigesimal, and of 60 for sexagesimal, etc. The original metric system of the 1790s made decimal scaling usual in Europe, though it had then been usual in China for a thousand years. The SI system, although nominally decimal through its metric heritage, is largely millesimal, i.e. in steps of 1 000. Steps of 100 are centesimal.

Meaning 10. The numbering system used by humans, which is based on 10 digits. In contrast, computers use binary numbers because it is easier to design electronic systems that can maintain two states rather than 10.
