Convert 109 µm to km

Converting micrometers (µm) to kilometers (km) is essential for various scientific and engineering applications. In this post, we will explore how to make this conversion easily and accurately.

µm Definition

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

km Definition

Kilometer (km) is a metric unit of length equal to 1,000 meters. It is widely used in geography, transportation, and everyday life to measure longer distances, such as the distance between cities or the length of roadways.

How to Convert 109 µm to km

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

1 µm = 1 x 10^-9 km

To convert 109 µm to km:

109 µm x (1 x 10^-9 km/µm) = 1.09 x 10^-7 km

Therefore, 109 micrometers is equal to 0.000000109 kilometers.

FAQs

What is the smallest unit of length?

The smallest commonly used unit of length is the picometer (pm), which is one-trillionth of a meter (10^-12 meters).

Why is it important to convert units?

Unit conversion is crucial for ensuring accurate measurements and comparisons in scientific research, engineering calculations, and everyday applications.

How do I convert kilometers back to micrometers?

To convert kilometers back to micrometers, multiply the number of kilometers by 1,000,000,000 (10^9).
