Convert 390 µm to km

Converting micrometers (µm) to kilometers (km) might seem complex at first, but it’s a straightforward process. This guide will help you understand the conversion and provide a simple method to achieve it.

µm Definition

Micrometer (µm) is a unit of length in the metric system, equal to one millionth of a meter. 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 unit of length in the metric system, equal to one thousand meters. It is widely used to measure distances on Earth, such as between cities or geographical features.

How to Convert 390 µm to km

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

1 µm = 1 x 10^-9 km

To convert 390 µm to km, you multiply by the conversion factor:

390 µm x 1 x 10^-9 km/µm = 3.9 x 10^-7 km

Therefore, 390 µm is equal to 3.9 x 10^-7 kilometers.

FAQs

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

The smallest commonly used unit in the metric system is the picometer (pm), which is one trillionth of a meter.

Why is the micrometer used in scientific measurements?

Micrometers are essential for scientific measurements because they allow for precise measurements of very small objects, such as cells, bacteria, and fibers.

How many micrometers are in a meter?

There are 1,000,000 micrometers in a meter, as one micrometer is one millionth of a meter.
