In this article, we’ll explain some key points about nm and cm and the method of conversion from nm(nanometer) to cm (centimeter).

## What is a nanometer (nm)?

In the metric system, A nanometer is a unit of Length or Distance. The symbol for nanometer is nm. The International spelling for this unit is ‘nanometre’.

## What is a centimeter (cm)?

In the metric system, A centimeter is a unit of Length or Distance. The symbol for centimeter is cm. The International spelling for this unit is ‘centimetre’.

## What’s 1 nanometer in centimeters?

When we want to convert from nanometers to centimeters, divide the value in nanometers by 10000000.

As, 1 nm = 1/10000000 = 1/10000000 = 1e-7 cm.

In addition, you can multiply the value in nanometers by 1 × 10-7.

So, 1 nm = 1 × 1 × 10-7 = 1 × 10-7 cm.

## How do we convert nanometers to centimeters?

If we want to convert a nanometer measurement to a centimeter measurement, then we need to divide the length by the conversion ratio.

Since, one centimeter is equal to 10,000,000 nanometers, you can use this simple formula to convert:

**centimeters** = **nanometers** ÷ **10,000,000**

[The length in cm is equal to the nm divided by 10,000,000]

Let’s take an example to understand properly!

**Problem**: Convert 450,000 nanometers to centimeters?

**Solution**:

**Step 1** (Formula)

cm = nm ÷ 10,000,000

**Step 2** (Put the Values)

= 450,000 ÷ 10,000,000

**Step 3** (Result)

= 0.045 or 0.0449999… cm

Or we can say – 450,000 nanometers (nm) is equal to 0.0449999999999 centimeters (cm).
