To convert a measurement in micrometers to a measurement in nanometers, multiply the length by the following conversion ratio: 1,000 nanometers/micrometer.

Since one micrometer is equal to 1,000 nanometers, you can use this simple formula to convert:

nanometers = micrometers × 1,000

The length in nanometers is equal to the length in micrometers multiplied by 1,000.

For example, here's how to convert 5 micrometers to nanometers using the formula above.
nanometers = (5 µm × 1,000) = 5,000 nm

How Many Nanometers Are in a Micrometer?

There are 1,000 nanometers in a micrometer, which is why we use this value in the formula above.

1 µm = 1,000 nm

Micrometers and nanometers are both units used to measure length. Keep reading to learn more about each unit of measure.

What Is a Micrometer?

One micrometer is equal to one-millionth (1/1,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The micrometer, or micrometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "micro" is the prefix for millionths, or 10-6. A micrometer is sometimes also referred to as a micron. Micrometers can be abbreviated as µm; for example, 1 micrometer can be written as 1 µm.

To get an idea of the actual physical length of a micrometer, one human hair is 40-50 µm thick, demonstrating how small this unit of measure is.

What Is a Nanometer?

One nanometer is equal to one-billionth (1/1,000,000,000) of a meter, which is defined as the distance light travels in a vacuum in a 1/299,792,458 second time interval.

The nanometer, or nanometre, is a multiple of the meter, which is the SI base unit for length. In the metric system, "nano" is the prefix for billionths, or 10-9. Nanometers can be abbreviated as nm; for example, 1 nanometer can be written as 1 nm.

The nanometer is an extremely small unit of length measurement, often used to measure things that are very small, such as the transistors and electrical pathways in computer processors and nanotechnology.

We recommend using a ruler or tape measure for measuring length, which can be found at a local retailer or home center. Rulers are available in imperial, metric, or a combination of both values, so make sure you get the correct type for your needs.
