Quick Summary

Use this when you need:

Report X-ray diffraction spacings that labs record in Å but journals prefer in nm
Convert semiconductor feature sizes between angstrom marketing numbers and nanometer process nodes
Compare molecular bond lengths in picometers against literature reported in Å

You’ll get:Length

How this is calculated

Formula:

length_target = length_source

In plain language:

Lengths are normalized to meters and rescaled into Å, nm, or pm; 1 Å equals 0.1 nm and 100 pm.

The formula is always visible so you can verify the math and explain your numbers to anyone who asks.

Angstrom to nanometer converter explained

Diffraction papers, lithography roadmaps, and materials tables flip between ångströms, nanometres, and picometres. This calculator keeps the scaling straight so you can quote lattice spacings or feature sizes without re-deriving factors.

How the conversion works

The ångström is $10^{-10}\,\text{m}$ ; the nanometre is $10^{-9}\,\text{m}$ . Because of that single power of ten, the relation is simple:

L_{\text{nm}} = L_{\text{\AA}} \times 0.1

L_{\text{\AA}} = L_{\text{nm}} \times 10

Picometres run another order down: $1\,\text{pm} = 0.01\,\text{\AA} = 0.001\,\text{nm}$ .

Units and conversions

Unit	Symbol	Metre relation
Ångström	Å	$1\,\text{\AA} = 1 \times 10^{-10}\,\text{m}$
Nanometre	nm	$1\,\text{nm} = 1 \times 10^{-9}\,\text{m}$
Picometre	pm	$1\,\text{pm} = 1 \times 10^{-12}\,\text{m}$
Metre	m	base unit

Worked examples

XRD peak spacing
Given $6.5\,\text{\AA}$ :
$L_{\text{nm}} = 6.5 \times 0.1 = 0.65\,\text{nm}$
Result: 0.65 nm.
Gate length in nanometres → ångströms
Given $3.2\,\text{nm}$ :
$L_{\text{\AA}} = 3.2 \times 10 = 32\,\text{\AA}$
Result: 32 Å.

Tips and pitfalls

Keep significant figures; semiconductor marketing often rounds aggressively, but physics work needs precision.
When mixing with lattice constants in picometres, remember pm is $10^{-12}$ m; avoid sliding a decimal the wrong way.
For spectroscopy, keep units consistent with the instrument output before converting for publication.
