How many nanometers are in 1 meter?

One meter contains exactly 109 nm (1 billion nanometers).

How do I convert meters to nanometers?

Multiply meters by 109 (1 billion) or move the decimal 9 places right.

When is this conversion important?

In semiconductor manufacturing (3 nm process nodes), molecular biology (DNA width 2.5 nm), and nanotechnology. Any time macro-scale devices contain nano-scale features.

Non-Frequently Asked Questions About Meters to Nanometers

Questions nobody should ask - but someone did.

A thumbnail is about 1 cm = 10⁷ nm. At 3 nm per transistor, about 3.3 million transistors fit across your thumbnail. Modern chips pack billions of transistors into areas smaller than your nail. Your fingernail is a parking lot for technology.
A marble is about 15 mm. Scaled up by 10⁹, a meter would be 15 million km - about 10% of the Earth-Sun distance. At marble-to-nanometer scale, a meter reaches 10% of the way to the Sun. Nano is really small.
Yes. IBM spelled 'IBM' using 35 individual xenon atoms in 1989. Each atom was about 0.4 nm wide. The letters were about 5 nm tall. Humans can manipulate individual atoms. The meter-to-nanometer gap has been crossed by human hands (with very expensive tools).
