A nanosecond (ns) is a unit of time in the International System of Units (SI) equal to one billionth of a second, that is, ⁠ 1 / 1 000 000 000 ⁠ of a second, or 10 −9 seconds. The term combines the SI prefix nano-indicating a 1 billionth submultiple of an SI unit (e.g. nanogram, nanometre, etc.) and second, the primary unit of time in the SI.

2010年1月13日 · NIST SI Measurement System Chart (2021) is a colorful chart explaining the 7 base units of the SI, prefix symbols, and features the Measurement League: Guardians of the SI. SI Prefix symbols are featured in the chart and used to represent smaller or larger units by factors that are powers of 10.

2014年8月11日 · The International System of Units (SI) introduced the prefixes ronna-, quetta-, ronto-, and quecto-in 2022. These additions are helpful for several reasons: Growing Needs in Data Science & Computing. The global volume of digital data is in zettabytes and soon requires ronnabytes and quettabytes.

2023年8月29日 · It allows the reduction of zeros of a very small number or a very larger number such as 0.000000001 meter and 7,500,000 Joules into 1 nanometer and 7.5 Megajoules respectively. These SI prefixes also have a set of symbols that precede unit symbol.

The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm), or nanometer (American spelling), is a unit of length in the International System of Units (SI), equal to one billionth (short scale) or one thousand million (long scale) of a meter (0.000000001 m) and to 1000 picometres.

Nano is a SI unit prefix meaning one billionth. Used primarily with the metric system, this prefix denotes a factor of 10⁻⁹ or 0.000000001. It is represented by the prefix nano or the symbol n. The prefix derives from the Greek term νᾶνος (Latin nanus), meaning dwarf.

Twenty SI prefixes are used to combine with units of measure. Each SI prefix name has an associated symbol which can be used in combination with the symbols for units of measure. Accordingly, the “kilo” symbol, k, may be used to denote km, kg, and kW, for representing kilometer, kilogram, and kilowatt respectively.
