100 a (ångströms) is equal to 10 nm (nanometers).
The conversion from ångströms to nanometers is done by recognizing that 1 ångström equals 0.1 nanometers. Therefore, multiplying the value in ångströms by 0.1 gives the equivalent length in nanometers.

Conversion Formula
The formula to convert ångströms (a) to nanometers (nm) is quite simple:
Nanometers (nm) = Ångströms (a) × 0.1
This works because 1 ångström is exactly 10-10 meters, and 1 nanometer equals 10-9 meters. Since a nanometer is ten times longer than an ångström, to convert ångströms to nanometers, multiply the ångström value by 0.1.
Example calculation for 100 a:
- Start with 100 a
- Multiply by 0.1: 100 × 0.1 = 10
- Result: 10 nm
Conversion Example
- Convert 250 a to nm:
- Multiply 250 by 0.1
- 250 × 0.1 = 25
- Therefore, 250 a = 25 nm
- Convert 50 a to nm:
- Multiply 50 by 0.1
- 50 × 0.1 = 5
- So, 50 a equals 5 nm
- Convert 123.4 a to nm:
- Multiply 123.4 by 0.1
- 123.4 × 0.1 = 12.34
- Thus, 123.4 a equals 12.34 nm
- Convert 80 a to nm:
- Multiply 80 by 0.1
- 80 × 0.1 = 8
- Hence, 80 a equals 8 nm

Conversion Definitions
Ångström (a): The ångström is a non-SI unit of length that equals 10-10 meters. Often used in physics and chemistry to express atomic scales or wavelengths of electromagnetic radiation, it provides a convenient measure for very small distances between atoms or molecules.
Nanometer (nm): A nanometer is a unit of length in the metric system, measuring 10-9 meters. It is widely used in science and technology to quantify things on atomic and molecular scales, like wavelengths of light and sizes of biological molecules.
Conversion FAQs
Why multiply ångströms by 0.1 to get nanometers?
Because 1 ångström equals 10-10 meters and 1 nanometer is 10-9 meters, the nanometer is ten times larger. Multiplying by 0.1 converts the smaller unit into the larger one by scaling down the value accordingly.
Can I convert nanometers back to ångströms?
Yes, converting nanometers to ångströms requires multiplying the nanometer value by 10. This reverses the previous conversion because 1 nm equals 10 a, scaling up the length measurement.
What common fields use ångströms and nanometers?
Ångströms are mostly found in fields like crystallography and atomic physics for precise atomic-scale measurements. Nanometers are used broadly in nanotechnology, optics, and semiconductor manufacturing, where slightly larger scales are relevant.
Is there any rounding error when converting 100 a to nm?
Since the conversion factor 0.1 is exact, converting 100 a to 10 nm involves no rounding. However, for decimal or non-integer values, rounding may occur when representing results to a fixed number of decimal places.
Are ångströms still used now nanometers exist?
Though nanometers are more common in modern measurements, ångströms remain popular in specific sciences due to historical usage and the convenience of expressing atomic distances without decimals.
