How to Convert Angstrom to Meter

1 angstrom = 1 × 10-10 meters

Meter = Angstrom × 1 × 10-10

Example: 690 Å × 1 × 10-10 = 6.9 × 10-8 m

Reverse Conversion

To convert meters back to angstroms:

  • Remember, 1 meter equals 1 × 1010 angstroms.
  • To convert 6.9 × 10-8 m to Å, multiply 6.9 × 10-8 x 1 × 1010, resulting in 690 Å.
About these units

Angstrom: Legacy unit equal to 10⁻¹⁰ meters, used in atomic and molecular measurements.

Meter: SI fundamental unit of length defined by the speed of light in vacuum (299,792,458 m/s).
