**Nanometer**

The **length unit** known as a **nanometer (nm)** is **one billionth** of a **meter (1/1,000,000,000 meters). **

The **size** of **atoms, molecules,** and other **extremely small** objects is frequently described **using this** extremely small **unit** of **measurement.** A **nanometer** is **comparable** to **being 100,000 times smaller** than a **human hair’s breadth** and **10 times smaller** than a **carbon atom’s** diameter.

**Nanosecond**

A **nanosecond** is **one billionth** of a **second** (1/1,000,000,000 seconds) in length.

It is **frequently used** to gauge the **length** of **extremely** **quick occurrences** or **processes** because it is a very **small unit** of **time.** A nanosecond is **roughly one-millionth** of a **millisecond** and **one-thousandth** of a **microsecond,** respectively.

**In Science and Technology**

**Nanometer**

In **science** and **technology,** the term **“nanometer”** is frequently **used** to **define** the **size** of very **small objects** and **structures,** such as the parts of **electronic devices** or the **architecture** of **biological cells.**

They are also utilized by **engineers** and **scientists** that work with materials and structures that are only a few nanometers in size in sectors like nanotechnology. When employed in calculations and measurements, the **metric unit** of a **nanometer** is **denoted** by the **letter “nm.”**

**Nanosecond**

In **science** and **technology,** the term **“nanosecond”** is frequently **used** to characterize the **speed** of **electronic devices** and other high-speed operations.

For instance, the **timing** of **electrical impulses** in computer networks and the **speed** of a **computer’s** central processing unit **(CPU)** are frequently measured in nanoseconds.

In **industries** like **telecommunications** and **radar technology,** where extremely quick **electromagnetic** energy **pulses** are **utilized** to transmit and **receive information,** the **nanosecond** is also **used.** When employed in calculations and measurements, the metric unit of a nanosecond is denoted by the letter **“ns.”**

**Properties of Nano**

**Summary**

The **nano** prefix **denotes** a **0.000000001 factor.** It is frequently used to refer to extremely small quantities or dimensions in the scientific and technological fields. For instance, one can **measure length** or **distance** with **nanometers, time** with **nanoseconds,** and **mass** with **nanograms.**

The nano prefix is used to **make extremely small quantities** easier to **communicate** about and **understands** than they might otherwise be.

You can **multiply** the **value** in **Nanos** by the **conversion factor** to **change** from a **unit** with the nano prefix to the base unit. You can **divide** the **value** in the **base unit by** the **conversion factor** to convert from the base unit to a unit with the nano prefix.

**Example for Nano**

**Example**

We are **given** time in **nanoseconds.** Let’s say **500ns. Convert** this **into seconds** and again **convert** it back **to nanoseconds** using the appropriate conversion factor.

**Solution**

To **convert** a quantity expressed in nanoseconds to seconds, you can **use** the **following conversion factor:**

**1 second** = 1,000,000,000 nanoseconds

To use this conversion factor, you can set up the conversion as follows:

X nanoseconds * (1 second / 1,000,000,000 nanoseconds) = **Y seconds**

Where **X** is the **quantity** in **nanoseconds** and **Y** is the quantity in **seconds.**

**Nanoseconds to Seconds**

To **convert 500 nanoseconds** to **seconds,** we can set up the conversion as follows:

500 nanoseconds * (1 second / 1,000,000,000 nanoseconds) = **0.0000005 seconds**

So, **500 nanoseconds** are **equal** to **0.0000005 seconds.**

**Seconds to Nanoseconds**

To **convert** a **quantity expressed** in **seconds** to **nanoseconds,** you can use the following conversion factor:

**1 nanosecond** = 1/1,000,000,000 seconds

To use this conversion factor, you can set up the conversion as follows:

X seconds * (1 nanosecond / 1/1,000,000,000 seconds) = **Y nanoseconds**

Where **X** is the **quantity** in **seconds** and **Y** is the quantity in **nanoseconds**.

For example, to convert 0.0000005 seconds to nanoseconds, we can set up the conversion as follows:

0.0000005 seconds * (1 nanosecond / 1/1,000,000,000 seconds) = **500 nanoseconds**

So, **0.0000005 seconds** is **equal** to **500 nanoseconds.**

These **conversion factors allow** you to **move back** and **forth** between **nanoseconds** and **seconds.** Just keep in mind to set up the conversion correctly and to utilize the suitable conversion factor.
