1 angstrom equals 1 × 10-10 meters.
An angstrom is a unit of length commonly used to express atomic scale distances, and it converts to meters by multiplying by 10 to the power of negative ten. This means one angstrom is one ten-billionth of a meter.

Conversion Formula
To convert angstroms to meters, multiply the angstrom value by 10-10. This is because one angstrom is defined as 0.0000000001 meters, or 1 × 10-10 meters.
The formula looks like:
meters = angstrom × 10-10
This works because the angstrom is designed to represent very small lengths, mostly atomic dimensions, and meters are the SI base unit for length.
Example calculation:
Convert 5 angstroms to meters:
- Start with 5 angstroms
- Multiply by 10-10: 5 × 10-10
- Result: 0.0000000005 meters or 5 × 10-10 meters
Conversion Example
- Convert 3 angstroms to meters:
- 3 × 10-10 = 0.0000000003 meters
- Multiply 3 by 0.0000000001
- Result: 3e-10 m
- Convert 12.5 angstroms to meters:
- 12.5 × 10-10 = 1.25 × 10-9 meters
- Multiply 12.5 by 0.0000000001
- Result: 0.00000000125 meters
- Convert 0.7 angstroms to meters:
- 0.7 × 10-10 = 7 × 10-11 meters
- Multiply 0.7 by 0.0000000001
- Result: 0.00000000007 meters
- Convert 20 angstroms to meters:
- 20 × 10-10 = 2 × 10-9 meters
- Multiply 20 by 0.0000000001
- Result: 0.000000002 meters

Conversion Definitions
Angstrom: An angstrom (symbol Å) is a length unit equal to 10-10 meters. It mostly used to express atomic and molecular sizes, wavelengths of light, and distances on a nanoscale. It is named after Anders Jonas Ångström, a Swedish physicist.
Meter: A meter (symbol m) is the base unit of length in the International System of Units (SI). It is defined by the distance light travels in vacuum during 1/299,792,458 seconds. Meters measure everyday distances from small objects to large scales.
Conversion FAQs
Why is the angstrom defined as 10-10 meters?
The angstrom was created to provide a convenient scale for atomic sizes and wavelengths of electromagnetic radiation. Since atoms and molecules are extremely small, using meters directly would be impractical, so the angstrom gives a simpler number for such tiny distances.
Can I use the conversion formula for negative angstrom values?
Yes, negative angstrom values can be converted to meters by the same formula. Negative length may represent direction or displacement in some contexts, like physics or engineering, so the conversion stays consistent.
Is the angstrom an SI unit?
No, the angstrom is not an official SI unit. It is accepted for use alongside SI, especially in fields like physics and chemistry, because of its convenient scale, but meters remains the SI base unit for length.
How precise is the conversion from angstrom to meter?
The conversion is exact because the angstrom is defined as exactly 10-10 meters. There is no approximation in the formula, so conversions are precise to the limits of numerical representation used.
Why do scientific instruments sometimes report distances in angstroms instead of meters?
Scientific instruments that measure atomic scale distances report in angstroms because it simplifies numbers and makes it easier to communicate very small lengths. Using meters would produce many zeros and increase complexity without adding clarity.
