How to Convert Meters to Nanometers

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

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

nanometers = meters × 1,000,000,000

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

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

How Many Nanometers Are in a Meter?

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

1 m = 1,000,000,000 nm

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

What Is a Meter?

According to the most recent 2019 definition, the meter is defined as the distance traveled by light in vacuum during a time interval with a duration of 1/299,792,458 of a second.[1] One meter is equal to 100 centimeters, 3.28084 feet, or 39.37 inches.

The meter, or metre, is the SI base unit for length in the metric system. Meters can be abbreviated as m; for example, 1 meter can be written as 1 m.

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.
