List of scientists whose names are used as SI units
List of scientists whose names are used as SI units is the list of those scientists whose names are assigned as the names of the international units by the International Committee for Weights and Measures. The International System of Units (abbreviated SI from French: Système international d'unités) is the most widely used system of units of measurement. There are seven base units and 22 derived units (excluding compound units). These units are used both in science and in commerce. Two of the base units and 17 of the derived units are named after scientists. By this convention, their names are immortalised. Below is the list of the scientists whose names are used as SI units.
Scientists and the SI units
|Base unit[note 1]||Derived unit|
Napier and Bell
Napier and decibel are two dimensionless units used to define relative amplitudes in logarithmic scales.[note 4] They are not SI units, but their usage together with SI units is permitted.
|John Napier||1550–1617||British (Scottish)||Magnitude (natural logarithmic)||neper (Np)|
|Alexander Graham Bell||1847–1922||British (Scottish)-American||Magnitude (common logarithmic)||bel (B)|

- There are 5 base units that are not named after people: kilogram, metre, second, mole and candela.
- As a rule, the units are written in lowercase letters, but symbols of units derived from the name of a person begin with a capital letter.
- The village he was born was a part of Austrian Empire, now it is in Croatia.
- Decibel is defined for power whereas neper is defined for voltage, current or pressure
