Interactive micrometers to kilometers conversion tool
The μm to km converter below can be used to quickly and easily convert micrometers to kilometers. Simply enter the number of micrometers you want to convert and the calculator will output the corresponding value in kilometers.
What is the conversion factor between micrometers and kilometers?
A conversion factor is used to change the units of a measured quantity without changing its value. It represents the ratio (or fraction) that expresses the relationship between two different units. A conversion factor is always equal to 1.
The relationship between micrometers and kilometers is 1e+9, such as:
Following the formula above, we can see that there are 1e+9 micrometers for every kilometer, and for every micrometer, there are 11e+9 kilometers (1e-9 km).
To convert from micrometers to kilometers, we turn our formula into a conversion factor that is equal to 1.
Both these fractions are equal to 1. The numerator and the denominator are equivalent, they are just expressed in different units.
Because we are converting from micrometer to kilometer, we will use the first fraction: 1 km1e+9 μm so that micrometers are canceled out. We then multiply the value in micrometers by this fraction to get the result in kilometers (see example).
Note that μm is in the denominator (bottom) of the conversion factor. This is important, you always want to have the unit you are converting from at the bottom and the unit you are converting to in the numerator (top).
You will find below how to use this ratio to convert from μm to km. Just remember for now that the conversion factor for converting from micrometers to kilometers is:
Which is bigger, a micrometer or a kilometer?
When it comes to measurements, there can be some confusion over which is bigger, a micrometer or an kilometer. To find out which one is larger, we must first convert one unit to the other and then compare them.
- 1 μm = 11e+9 km = 1e-9 km
- 1e-9 kilometer is smaller than 1 kilometer.
- 1 micrometer is, therefore, smaller than 1 kilometer.
- To be more specific, a kilometer is 1e+9 times bigger than a micrometer.

How to convert micrometers to kilometers?
Multiplying any value by 1 will get you the same value back. You can do that one time or multiple times.
For example:
- 27 x 1 = 27
- 154 x 1 x 1 x 1 = 154
Multiplying by 1 is the first step in any unit conversion problem. The second step is to replace the number 1 with the conversion factor that is also equal to 1.
For example, if we want to convert 1e+6 micrometers into kilometers we multiply 1e+6 μm by the conversion factor of 1 km1e+9 μm
By replacing the number 1 with the conversion factor, micrometers are canceled out and we get the result in kilometers. And since the conversion factor is equal to 1, multiplying it with the original value won't change its magnitude and will only change its unit.
Based on this, we can conclude that 1e+6 micrometers are equal to 0.001 kilometers.
Remember:
- When converting from micrometers to kilometers, we use 1 km1e+9 μm as a conversion factor.

How to convert 51 micrometers to kilometers?
We multiply 51 by the factor of 1
We replace the number 1 with the conversion factor for micrometers to kilometers
We multiply 51 micrometers by the conversion factor. Having micrometers in the denominator allows us to cancel out the undesired units (μm) leaving only kilometers in the final result.
Answer: There are 5.1e-8 kilometers in 51 micrometers
How many kilometers are in 465 micrometers?
Multiply 465 by the conversion factor. Make sure the unwanted unit (μm) is in the denominator.
This allows us to cancel out the micrometers (μm) and leave the kilometers (km)
Answer: There are 4.65e-7 kilometers in 465 micrometers
