Convert 989 µm to km

Converting measurements between different units can be essential for various scientific and practical applications. In this post, we will convert 989 micrometers (µm) to kilometers (km) and explain the process involved.

µm Definition

Micrometer (µm) is a unit of length in the metric system equal to one millionth of a meter (10^-6 m). It is commonly used in fields such as biology, material science, and engineering to measure small distances, such as the size of cells or the thickness of materials.

km Definition

Kilometer (km) is a unit of length in the metric system equal to one thousand meters (10³ m). It is widely used in geography and transportation to measure distances between locations, such as the length of roads or the distance between cities.

How to Convert 989 µm to km

To convert micrometers to kilometers, you can use the following formula:

1 µm = 1 x 10^-9 km

Now, to convert 989 µm to km:

989 µm x (1 x 10^-9 km / 1 µm) = 9.89 x 10^-7 km

Therefore, 989 µm is equal to 9.89 x 10^-7 kilometers.

FAQs

What is a micrometer used for?

A micrometer is commonly used to measure small distances, such as the diameter of cells, the thickness of materials, and in precision engineering applications.

Why is kilometer a preferred unit for distance?

Kilometers are preferred for measuring longer distances because they provide a more manageable number compared to using meters, making it easier to communicate distances in geography and travel.

How many micrometers are in a kilometer?

There are 1,000,000,000 micrometers in a kilometer, as 1 km equals 1 x 10³ meters, and 1 meter equals 1,000,000 micrometers.
