## How to perform key conversions involving length measurements

The formulas for conversion are represented below:

### Kilometer to Micrometer Formula

µm = km x 1000000000

Example: 30 kilometers in Micrometers:

µm = km x 1000000000

µm = 30 x 1000000000

µm = 3000000000

### Micrometer to Kilometer Formula

km = µm / 1000000000

Example: 1500 Micrometers in kilometers:

km = µm / 1000000000

km = 1500 / 1000000000

km = 1,5 x 10-5

## Frequently asked questions involving length and distance

### 1.5 km in Micrometers

Considering that 1 kilometer is equivalent to 1000000000 micrometers, you can use a rule of three to get that 1.5 km equals 1500000000 micrometers.

1 km - 1000000000 µm

1,5 km - x

Apply the rule of three and get:

x km = 1.500.000.000 µkm2

x = 1.500.000.000 µm

### 1000000 Micrometers equal how many Kilometers?

If every 1,000,000,000 Micrometers we have 1 kilometer, just divide the number of Micrometers (1000000) by 1000000000, so you will obtain that 1000000 µm equals 0.01 km. Observe the calculation below:

km = µm / 1000000000

Km = 1000000 / 1000000000

km = 0,01
