The tesla (T), the standard unit of magnetic flux density, is named for Nikola Tesla.
The newton (N), the SI unit of force, is named for Sir Isaac Newton.
The pascal (Pa), the unit of pressure, is named for Blaise Pascal.
The henry (H), the Standard International (SI) unit of inductance, is named for Joseph Henry.
