List of scientists whose names are used as non SI units

Most of the physical units are named after great scientists. By this convention, their names are immortalised. The scientists whose names are used in SI units are listed in List of scientists whose names are used as SI units. Below is the list of the scientists whose names are used in non-SI units.

Notes

↑ As a rule, the units are written in lowercase letters. But, symbols of units derived from a personal name always begin with a capital letter.
↑ Neper and decibel are dimensionless units
