Exameter
An exameter is a unit of length in the metric system equal to 10^18 meters.
History/Origin
The prefix "exa-" for 10^18 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The exameter is used in astronomy to measure the vast distances between galaxies.
Nanometer
A nanometer is a unit of length in the metric system, equal to one billionth of a meter.
History/Origin
The term “nanometer” gained prominence in the late 20th century with the advent of nanotechnology and the development of microscopes capable of observing objects at that scale.
Current Use
The nanometer is commonly used to express dimensions on an atomic and molecular scale. It is used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum and in the field of nanotechnology.
