## How to perform key conversions involving length measurements

The formulas for conversion are represented below:

### Kilometers to Nanometers Formula

nm = km x 1012

Example: 30 kilometers in meters:

nm = km x 1.000.000.000.000

nm = 30 x 1.000.000.000.000

nm = 3x10-13

### Nanometers to Kilometers Formula

km = nm / 1012

Example: 1500 Nanometers in kilometers:

km = nm / 1.000.000.000.000

km = 1500 / 1.000.000.000.000

km = 1,50x10-9

## Frequently asked questions involving length and distance

### 1.5 km in Nanometers

Considering that 1 kilometer is equivalent to 1012 nanometers, you can use a rule of three to obtain that 1.5 km equals 1.5x1012 nm.

1 km - 1012 nm

1,5 km - x

Apply the rule of three and get:

x km = 1,5 kmnm

x = 1,5x1012 nm

### 100 Nanometers is equal to how many Kilometers?

If every 1,000,000,000,000 Nanometers we have 1 kilometer, just divide the number of Nanometers (100) by 1000, so you will get that 100 m equals 0.1 km. Observe the calculation below:

km = nm / 1.000.000.000.000

Km = 100 / 1.000.000.000.000

km = 1x10-10
