Nano (n)
Definition: An SI prefix denoting a factor of 10⁻⁹ — one billionth of the base unit.
History: Adopted by the CGPM in 1960, giving science a standard name for the extremely small quantities being measured as instrumentation improved.
Current use: Central to modern nanotechnology and semiconductor manufacturing (nanometers describe transistor feature sizes), and to timing in computing (nanoseconds).
None (base unit) (—)
Definition: The unprefixed base value — a multiplier of exactly 1, representing a quantity with no SI prefix attached at all (e.g. a plain gram, meter, or watt rather than a kilogram, kilometer, or milliwatt).
History: This isn't a historical unit in its own right — it's simply the reference point the entire SI prefix ladder is built around, against which every prefix above and below is defined as a power of ten.
Current use: Used as the baseline whenever a quantity is expressed without any prefix, and as the anchor point for converting any other prefix on this page to any other.

About These Parameters
- Value
- The number of "From" prefix units you want to re-express in the "To" prefix. Since prefixes are just multiplier scales, this value can represent anything from a physical quantity's leading digits to a plain abstract number.
- From Unit
- The SI prefix your value is currently scaled by — for example, the "kilo" in "kilogram" or the "nano" in "nanosecond," entered here without the base unit attached.
- To Unit
- The SI prefix you want the value re-expressed in. Use the swap button to flip From and To instantly, handy when converting a datasheet figure from one prefix scale to another.
How Prefix Conversion Works
The Formula
Every SI prefix is defined by a fixed power-of-ten multiplier relative to the unprefixed base value. To convert a value from one prefix scale to another:
result = value × (multiplier of "From" prefix ÷ multiplier of "To" prefix)
For Nano → None (base unit): multiply by 1E-09. For example, 1 n × 1E-09 = 1E-09 —.
A History of Powers of Ten
The original six metric prefixes — kilo, hecto, deka, deci, centi, milli — were adopted by the French Academy of Sciences in 1795 alongside the metric system itself. As science and industry needed to describe ever-larger and ever-smaller quantities, the CGPM (Conférence Générale des Poids et Mesures) extended the table repeatedly: mega and micro in 1960 when the modern SI was formalized, giga and nano the same year, tera and pico following soon after, then peta/femto (1975), exa/atto (1975), and finally zetta/zepto and yotta/yocto in 1991 — the classical range covered on this page. In 2022 the CGPM went further still, adding ronna/ronto and quetta/quecto to keep pace with data-storage and astrophysical quantities that had begun to outgrow even yotta.
Why a Prefix-Only Converter Is Useful
Every other unit converter on this site attaches these same prefixes to one specific base unit — grams, watts, bytes, farads — because that's how the prefix is actually used in practice. But the underlying math of "how much bigger is giga than mega" never changes no matter which unit it's modifying, so it's often faster to reason about the prefix scale on its own: quickly checking that a "giga" figure is a billion and not a million, or converting a "nano" measurement from one datasheet into the "micro" scale used by a different one, without needing to know or care what physical quantity either figure describes.
Example
1 n equals 1E-09 —. Whatever base unit these prefixes are actually attached to — grams, bytes, watts, seconds — the same multiplier ratio applies: 1 kilo- is always 1,000 times 1 (unprefixed), and 1 mega- is always 1,000 times 1 kilo-, regardless of the quantity being measured.
Frequently Asked Questions
How many None (base unit) are in 1 Nano?
1 Nano (n) equals exactly 1E-09 None (base unit) (—).
Is giga a billion or a million?
Giga is always a billion (10⁹) times the base unit — a common point of confusion is with "mega," which is a million (10⁶). The two are frequently mixed up in casual conversation about data storage and computing speed, which is exactly the kind of mistake this converter is designed to catch.
Does this converter work for any unit, like grams or bytes?
Yes — this converter deliberately ignores the underlying unit and works purely with the multiplier scale. "1 kilo- to mega-" gives the same ratio (0.001) whether you mentally attach it to grams, watts, bytes, or any other quantity, because the prefix's multiplier is independent of what it's modifying.
What does "None (base unit)" mean in the unit list?
"None (base unit)" represents a value with no prefix attached at all — a plain gram, meter, or watt rather than a kilogram, kilometer, or milliwatt. It's included so you can convert directly between an unprefixed value and any prefixed scale, such as figuring out how many kilo- units equal one plain (unprefixed) unit.
Are ronna, ronto, quetta, and quecto included here?
Not yet — this page covers the classical SI prefix range from yotta (10²⁴) down to yocto (10⁻²⁴), which was complete from 1991 until 2022. The newer 2022 additions (ronna/ronna-, quetta/quecto) sit beyond even yotta and yocto and aren't included in this table.
