Convert 126 µm to km

Converting units of measurement is essential for various scientific and engineering applications. In this post, we will demonstrate how to convert 126 micrometers (µm) to kilometers (km), providing clarity on the conversion process and its significance.

µm Definition

Micrometer (µm), also known as a micron, is a unit of length in the metric system equal to one millionth of a meter (1 µm = 10^-6 m). It is commonly used in fields such as biology, materials science, and semiconductor manufacturing to measure microscopic distances.

km Definition

Kilometer (km) is a unit of length in the metric system equivalent to 1,000 meters (1 km = 10³ m). It is widely used in geography, transportation, and environmental science to measure longer distances.

How to Convert 126 µm to km

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

1 µm = 1 x 10^-9 km

To convert 126 µm to km, multiply 126 by 1 x 10^-9:

126 µm x 1 x 10^-9 km/µm = 1.26 x 10^-7 km

Therefore, 126 µm is equal to 1.26 x 10^-7 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 (1 pm = 10^-12 m).

Why do we use micrometers in science?

Micrometers are used in science to measure very small objects or distances, such as cells, bacteria, and other microscopic entities, allowing for precise analysis and research.

How many micrometers are in a kilometer?

There are 1,000,000,000 micrometers in a kilometer (1 km = 10⁹ µm).
