Convert 309 µm to km

Converting measurements is essential for various fields, including science, engineering, and everyday applications. In this post, we will explore how to convert 309 micrometers (µm) to kilometers (km) effectively.

µm Definition

Micrometer (µm) is a unit of length in the metric system, equal to one-millionth of a meter (0.000001 m). It is commonly used in fields such as biology, materials science, and engineering to measure small distances, such as the size of cells or the thickness of materials.

km Definition

Kilometer (km) is a metric unit of length equal to one thousand meters (1,000 m). It is widely used around the world for measuring distances in geography, travel, and various scientific applications.

How to Convert 309 µm to km

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

1 µm = 1 x 10^-9 km

To convert 309 µm to km:

309 µm x 1 x 10^-9 km/µm = 3.09 x 10^-7 km

Therefore, 309 µm is equal to 3.09 x 10^-7 kilometers.

FAQs

What is the smallest unit of length in the metric system?

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

How many micrometers are in a meter?

There are 1,000,000 micrometers (µm) in one meter (m).

Why is the micrometer important in science?

The micrometer is crucial in science and engineering for measuring very small lengths, such as cell sizes, wavelengths of light, and material thicknesses, enabling precision in research and manufacturing.
