Use the converter below to change any angstroms value into meters instantly — with formula, conversion table, and real-world examples.

1.0000e-10

Conversion formula

Forward
meters = angstroms × 1.0000e-10
Reverse
angstroms = meters × 10,000,000,000

Example: 10 Å × 1.0000e-10 = 1.0000e-9 m.

Angstrom

Å

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.

Meter

m

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 Å = 0.1 nm = 100 pm. Modern SI recommends nm or pm for new publications.
  • The ångström is named after the Swedish physicist Anders Jonas Ångström.
  • For quick atomic-scale intuition: most atoms are 1–3 Å across.

Avoid these

  • Mixing up Å with µm — the scale differs by 10,000×.
  • Using Å for anything macroscopic — always use nm or mm for things visible under a light microscope.
  • Forgetting the diacritic in "Ångström" — the symbol Å avoids spelling issues.

Frequently asked questions

How many meters in a angstrom?
One angstrom equals 1.0000e-10 meters.
How do I convert angstroms to meters?
Multiply the angstrom value by 1.0000e-10 to get the equivalent in meters.
What is 100 angstroms in meters?
100 angstroms equals 1.0000e-8 meters.
Is a angstrom bigger than a meter?
No. 1 angstrom equals 1.0000e-10 meters, so one angstrom is smaller.
How to convert angstroms to meters without a calculator?
Multiply by 0 for a quick estimate; use a calculator for precise results.
