Forward

angstroms = nanometers × 10

Reverse

nanometers = angstroms × 0.1

Example: 10 nm × 10 = 100 Å.

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.

Angstrom

The angstrom equals 10⁻¹⁰ meters or 0.1 nanometers. It is used in chemistry and crystallography for atomic and molecular dimensions. The Bohr radius — the characteristic size of a hydrogen atom — is 0.529 Å. Covalent bond lengths are typically 1–2 Å.

Real-world: A water molecule is about 1 Å across. The covalent bond in H₂ is 0.74 Å. X-ray wavelengths are 0.1–100 Å.

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 angstroms in a nanometer?

One nanometer equals 10 angstroms.

How do I convert nanometers to angstroms?

Multiply the nanometer value by 10 to get the equivalent in angstroms.

What is 100 nanometers in angstroms?

100 nanometers equals 1,000 angstroms.

Is a nanometer bigger than a angstrom?

Yes. 1 nanometer equals 10 angstroms, so one nanometer is larger.

How to convert nanometers to angstroms without a calculator?

Multiply by 10 for a quick estimate; use a calculator for precise results.
