How many kilometers are there in a micrometer? Use this online tool to quickly convert from micrometers to kilometers (μm to km) and vice versa.
How Many Kilometers in a Micrometer?
There are exactly 0.000000001 kilometers in a micrometer. In scientific notation, this is expressed as 1×10-9.
To convert any given number of micrometers to kilometers accurately, simply multiply the number of micrometers by the conversion factor to obtain the mathematically equivalent length or distance in kilometers.
The reverse operation—dividing the given number of kilometers by the conversion factor—will allow you to successfully convert from kilometers to micrometers without fail.
Difference Between Micrometers and Kilometers
The primary distinctions between micrometers and kilometers are the units of length they represent, their respective uses and applications, and conversion factors.
| Characteristics | Micrometers (μm) | Kilometers |
|---|---|---|
| Unit of Length | Also known as micron, a micrometer is the second smallest metric unit of length. Its prefix, micro, means one-millionth, which denotes that it is one-millionth of a meter. Most humans cannot see anything smaller than 40 micrometers without any scientific tools such as the microscope. | A kilometer is a unit of great length and distance. The term “myriamètre,” which denoted 10,000 meters, was largely preferred to the kilometer for daily use. It wasn’t until the prefix “myria-” was abolished in 1935 that the kilometer was formally and widely recognized unit of length for longer measurements. |
| Uses and Applications | Used commonly to measure infrared radiation wavelengths and sizes of microorganisms such as bacteria and cells | Used to measure virtually any considerably long geographical distances in most of the world |
| Conversion Factor | 1 micrometer is 0.000000001 kilometers | 1 kilometer is 1000000000 micrometers |
Similarity Between Micrometers and Kilometers
Both micrometers and kilometers are part of the metric system, formally known as the International System of Units (SI). This system of measurement has virtually replaced the Imperial system worldwide.
Its unit of length is based on the meter and uses decimal-based multipliers to denote longer or shorter measurements. In this case, “micro-” indicates one-millionth while “kilo-” means one thousand.
How to Convert Micrometers to Kilometers?
The conversion factor of 1 micrometer = 0.000000001 kilometers can be used to convert between micrometers and kilometers. Refer to the subsequent mathematical process for a more thorough explanation:
Formula:
Kilometers = Micrometers × 0.000000001
Task:
Convert 25,498 micrometers to kilometers
Calculation:
Number of Kilometers = 25498 × 0.000000001 = 0.000025948 km
Therefore, 25,498 micrometers is equivalent to 0.000025948 kilometers.
