Nanowebers per Meter (NW/m)

Nanowebers per Meter (NW/m)

The standard unit in measuring the amount of magnetic strength on analog tape. A Weber is a unit of magnetic strength, but it is too large a unit to apply to the magnetism in tape recorders, so nanowebers is used instead. Nanowebers per meter of tape effectively describes the signal strength that is being recorded to tape.
