Angstrom (Å)
Length
Traceable to the metre, defined by fixing the speed of light in vacuum at 299 792 458 m/s. Imperial lengths derive from the 1959 international yard (0.9144 m exactly).

How to Convert Angstrom to Chain
To convert from Angstrom (Å) to Chain (ch), multiply the value by 4.970970e-12.
Formula: ch = Å × 4.970970e-12
Reverse: Å = ch × 2.011680e+11
Step-by-Step Example
- Start with your value in Angstrom. For example: 5 Å
- Multiply by the conversion factor: 5 x 4.970970e-12
- The result is: 2.485485e-11 ch
About Angstrom
The angstrom (Å) equals 10⁻¹⁰ metres, or 0.1 nanometres — roughly the diameter of a hydrogen atom, which is why it survives in crystallography and spectroscopy.
Common uses: crystallography, atomic physics, semiconductors.
About Chain
Gunter's chain equals 66 feet (20.1168 m) and underpins the US Public Land Survey System: 10 square chains make one acre.
Common uses: land surveying, cadastral records, cricket pitch length.
