1.0000e-9

Conversion formula

Forward

meters = nanometers × 1.0000e-9

Reverse

nanometers = meters × 1,000,000,000

Example: 10 nm × 1.0000e-9 = 1.0000e-8 m.

From

Nanometer

The nanometer equals one billionth of a meter. Visible light spans 380–700 nm. Modern semiconductors are manufactured on 3–5 nm process nodes. Gold atom diameter is 0.29 nm. The nanometre is the natural scale for atomic physics and nano-engineering.

Real-world: Visible light is 380–700 nm. Apple's A17 Pro chip uses a 3 nm process. The DNA double helix is 2 nm wide.

Meter

The meter is the base SI unit of length. It was first defined in 1793 as one ten-millionth of the distance from the equator to the North Pole through Paris. Today it is defined as the distance light travels in vacuum in 1/299,792,458 of a second — a definition tied directly to the universal speed of light. The meter is the foundation of the metric system used by 95% of the world.

Real-world: A standard door is about 2 metres tall. An Olympic swimming pool is exactly 50 metres long. The Eiffel Tower is 330 metres tall.

Tips & common mistakes

Quick tips

1 nm = 10 Ångströms = 0.001 µm. Chemists often prefer Ångströms for bond lengths.
Chip "5 nm" is a marketing term — the actual feature size differs by manufacturer.
Red light is 700 nm; violet is 380 nm; UV is below 380 nm.

Avoid these

Assuming "3 nm" describes a single transistor width — it is a process-node name.
Confusing nm (length) with nM (nanomolar concentration).
Using nm for anything visible to the naked eye — switch to µm or mm.

Frequently asked questions

How many meters in a nanometer?

One nanometer equals 1.0000e-9 meters.

How do I convert nanometers to meters?

Multiply the nanometer value by 1.0000e-9 to get the equivalent in meters.

What is 100 nanometers in meters?

100 nanometers equals 1.0000e-7 meters.

Is a nanometer bigger than a meter?

No. 1 nanometer equals 1.0000e-9 meters, so one nanometer is smaller.

How to convert nanometers to meters without a calculator?

Multiply by 0 for a quick estimate; use a calculator for precise results.
