100 a (angstroms) equals 10 nanometers (nm).
The conversion from angstroms to nanometers involves recognizing that one angstrom is one tenth of a nanometer. Therefore, multiplying the value in angstroms by 0.1 gives the equivalent length in nanometers.

Conversion Formula
The formula to convert angstroms (a) to nanometers (nm) is:
nm = a × 0.1
Since 1 angstrom equals 0.1 nanometers, multiplying any value in angstroms by 0.1 converts it to nanometers. This works because angstroms and nanometers are both units to measure length at atomic scales, but nanometers are ten times larger.
Example calculation for 100 a:
- Take the value in angstroms: 100 a
- Multiply by 0.1: 100 × 0.1 = 10 nm
- The result is 10 nanometers.
Conversion Example
- Convert 50 a to nm:
- 50 a × 0.1 = 5 nm
- So, 50 angstroms is 5 nanometers.
- Convert 125 a to nm:
- 125 a × 0.1 = 12.5 nm
- This means 125 angstroms equals 12.5 nanometers.
- Convert 80 a to nm:
- 80 a × 0.1 = 8 nm
- Therefore, 80 angstroms converts to 8 nanometers.
- Convert 90 a to nm:
- 90 a × 0.1 = 9 nm
- 90 angstroms equals 9 nanometers.

Conversion Definitions
a (angstrom): An angstrom (symbol: a) is a unit of length measuring 10^-10 meters or 0.1 nanometers. It is widely used in physics and chemistry to express atomic-scale distances like bond lengths and atomic radii because it fits well the scale of atoms and molecules.
nm (nanometer): A nanometer (symbol: nm) equals one billionth of a meter (10^-9 meters). It is used to measure very small lengths such as wavelengths of light, sizes of molecules, and nanoscale structures in science and engineering fields, bridging atomic and microscopic scales.
Conversion FAQs
Why do I multiply angstroms by 0.1 to get nanometers?
Because one angstrom is defined as 0.1 nanometers. So when you multiply any length value in angstroms by 0.1, you convert it to the larger unit nanometers. The factor 0.1 comes from the ratio of their sizes, with nanometers being ten times bigger than angstroms.
Can I convert nanometers back to angstroms easily?
Yes, to convert nanometers to angstroms, multiply the nanometer value by 10 because one nanometer equals 10 angstroms. This reverses the original conversion, allowing switching between the units quickly.
Are angstroms still used today in science?
Angstroms are still common in fields like crystallography and molecular biology for expressing atomic-scale distances. But in many cases, nanometers or picometers are preferred, depending on the scale and precision needed.
Is there any difference in precision when converting between a and nm?
The conversion is exact mathematically (1 a = 0.1 nm), so no precision is lost. However, the precision depends on how many decimal places the original measurement has and how you round the converted number.
What instruments measure lengths in angstroms or nanometers?
Devices like electron microscopes, X-ray diffraction instruments, and atomic force microscopes measure lengths at these scales. Their readings can be expressed in angstroms or nanometers depending on conventions used in the field or reported data.
