What are angstroms?

Answer 1

An angstrom is a very small unit of length named after Anders Angstrom, often used in physics or chemistry to give the sizes of atoms, chemical bonds or wavelengths of radiation.

one angstrom = 1 x 10-10 meters

Answer 2

The Angstom unit is a unit of length equal to 10E-10 metres. It is used to express wavelengths of light in and around the visible spectrum.

In modern times the nanometre (nm) is often widely used, 10E-9 metres, which is ten times larger.

Answer 3

It's a more or less obsolete unit. A unit of length, equal to 10 to the power -10 meters (0.1 nm). Nowadays, scientists are more likely to use µm or nm, where angstroms were used in the past - typically for wavelengths of light.

Answer 4

An angstrom is 10-10 meters or 1/10th of a nanometer.

Answer 5

An ångström is is a unit of measurement that is defined as one trillionth of a meter. It's small size makes it useful in molecular measurements.

Answer 6

one millionths of a milimeter
