1 angstrom is equal to 1 × 10-10 meters (m).
An angstrom is a unit of length often used to measure atomic scales, and it converts to meters by multiplying with 10 to the power of negative ten. This tiny length demonstrates how small atomic structures are compared to everyday measurements.

Conversion Formula
The angstrom to meter conversion formula is based on the relation:
1 angstrom (Å) = 1 × 10-10 meters (m)
This means to convert any value in angstroms to meters, multiply it by 10 raised to the power of -10.
Why does it works? Because the angstrom was defined historically as one ten-billionth of a meter, so the formula reflects that fixed ratio.
Step-by-step example for converting 5 angstroms:
- Start with the value: 5 Å
- Multiply by 10-10: 5 × 10-10
- Calculate the result: 5 × 0.0000000001 = 0.0000000005 m
Conversion Example
- 3 Å to meters:
- 3 × 10-10 = 0.0000000003 m
- Multiply 3 by 0.0000000001, gives 0.0000000003 m.
- 10 Å to meters:
- 10 × 10-10 = 0.0000000010 m
- The value times the conversion factor equals 1e-9 meters.
- 0.5 Å to meters:
- 0.5 × 10-10 = 0.00000000005 m
- Half an angstrom converts to five times ten to the negative eleven meters.
- 20 Å to meters:
- 20 × 10-10 = 0.0000000020 m
- Simply multiply twenty by the conversion factor to get meters.

Conversion Definitions
Angstrom: The angstrom (symbol Å) is a length unit equal to 10-10 meters. It’s commonly used to express atomic and molecular sizes, wavelengths of light, and distances at the nanoscale. It is named after the Swedish physicist Anders Jonas Ångström.
Meter: The meter (symbol m) is the fundamental SI unit of length, defined by the distance light travels in vacuum in 1/299,792,458 seconds. The meter measures lengths in everyday life and scientific measurements, ranging from very small to very large scales.
Conversion FAQs
Is the angstrom still used in modern science?
Yes, the angstrom remains common in fields like physics, chemistry, and materials science for specifying atomic distances and wavelengths. Despite SI units preference, its scale fits atomic dimensions perfectly, so scientists find it convenient for expressing very small lengths.
Can I convert angstroms to other length units besides meters?
Absolutely, angstroms convert to nanometers, centimeters, and inches by applying their respective factors. For example, 1 Å equals 0.1 nanometers. Conversion requires multiplying or dividing by the correct ratio for each unit, not just meters.
Why is the conversion factor 10-10?
The angstrom was defined as one ten-billionth of a meter for historical reasons tied to spectroscopy and atomic measurements. This fixed value makes converting straightforward by multiplying any angstrom value by 10-10 to get meters.
Are negative angstrom values physically meaningful?
Negative angstrom values may be used in calculations or models representing direction or displacement relative to a reference point. Physically, length can’t be negative, but in mathematical contexts, negative lengths show position or vector direction.
How precise is the conversion from angstrom to meter?
The conversion is exact by definition because the angstrom is defined in terms of meters. However, measurement precision depends on instruments and context, but mathematically, 1 Å = 1 × 10-10 m without uncertainty.
