Convert SI, imperial, US customary, astronomical, scientific, and historical length units.
Context values
Some unit families need one extra value for a physically accurate result.
An angstrom is 1e-10 meters.
Result = input x 0.01 / 1e-10.
Length uses the meter as the base unit.

About Converting Centimeters to Angstroms
Centimeter and Angstrom both measure length. Centimeter is typically associated with standard small-length unit worldwide except the US, while Angstrom is typically associated with widely used internationally in chemistry, crystallography, and atomic/molecular physics.
Formula
angstroms = centimeters × 100000000
This factor comes from each unit's defined relationship to the category's base unit: 1 centimeter equals 0.01 base units, and 1 angstrom equals 1e-10 base units, so dividing one by the other gives the direct centimeter-to-angstrom factor of 100000000.
Simple example
1 cm × 100000000 = 100,000,000 A
1 centimeter = 100,000,000 angstroms.
Real-world example
10 cm × 100000000 = 1,000,000,000 A
10 centimeters = 1,000,000,000 angstroms.

| Centimeter (cm) | Angstrom (A) |
|---|---|
| 1 cm | 100,000,000 A |
| 5 cm | 500,000,000 A |
| 10 cm | 1,000,000,000 A |
| 21.0975 cm | 2,109,750,000 A |
| 42.195 cm | 4,219,500,000 A |
| 100 cm | 10,000,000,000 A |
Reverse conversion: Angstrom to Centimeter
1 A × 1e-8 = 1e-8 cm
1 angstrom = 1e-8 centimeters.
centimeters = angstroms × 1e-8

Centimeter vs. Angstrom
| Aspect | Centimeter | Angstrom |
|---|---|---|
| Family | SI derived (metric prefix) unit | non-SI unit, still common in chemistry and crystallography |
| Typical use | Everyday small-object and body measurement (height, clothing sizes) outside the US | Atomic and ionic radii in chemistry |
| Where it's used | Standard small-length unit worldwide except the US | Widely used internationally in chemistry, crystallography, and atomic/molecular physics |
Understanding the Centimeter
Centimeter (cm) measures distance. A centimeter is one-hundredth of a meter. It is classified as a SI derived (metric prefix) unit.
Where it's used: Standard small-length unit worldwide except the US
Uses of the Centimeter today
- Everyday small-object and body measurement (height, clothing sizes) outside the US
- Construction and manufacturing tolerances internationally
History of the Centimeter
The centimeter follows directly from the meter via the 'centi-' SI prefix (10⁻²), introduced with the metric system in the 1790s.
Historical origin. Centimeter was not the invention of a single named person; it developed through the process described above.
Understanding the Angstrom
Angstrom (A) measures length. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. It is classified as a non-SI unit, still common in chemistry and crystallography.
Where it's used: Widely used internationally in chemistry, crystallography, and atomic/molecular physics
Uses of the Angstrom today
- Atomic and ionic radii in chemistry
- Chemical bond-length measurements
- X-ray crystallography and wavelength measurements
History of the Angstrom
The angstrom is named after Anders Jonas Ångström (1814–1874), a Swedish physicist and one of the founders of spectroscopy, who used the unit in his 1868 atlas of the solar spectrum.
Historical origin. Angstrom was not the invention of a single named person; it developed through the process described above.

Frequently asked questions
How many angstroms are in 1 centimeter?
1 centimeter equals 100,000,000 angstroms, using the exact defined conversion factor rather than an estimate.
How do I convert centimeter to angstrom?
Multiply the centimeter value by 100000000. The converter above does this instantly to whatever precision you set.
How do I convert angstrom back to centimeter?
Use the reverse factor: 1 angstrom equals 1e-8 centimeters. You can also use the swap control in the converter above to flip the direction instantly.
What is a centimeter?
Centimeter (cm) measures distance. A centimeter is one-hundredth of a meter. It is classified as a SI derived (metric prefix) unit.
What is a angstrom?
Angstrom (A) measures length. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. It is classified as a non-SI unit, still common in chemistry and crystallography.
Is the centimeter to angstrom conversion exact?
Yes. Equal to exactly 10⁻¹⁰ meters (0.1 nanometers) — a scale convenient for describing atomic radii, bond lengths, and crystal structures. That fixed definition is what the converter above uses, so any rounding you see is a display choice, not a limitation of the math.
Where is the centimeter still used today?
Standard small-length unit worldwide except the US
