Gramme

Gramme can refer to several different concepts and entities, primarily associated with the unit of mass and notable individuals. Below are the primary contexts in which "Gramme" is used:

Unit of Mass

The gramme (or gram) is a unit of mass in the International System of Units (SI). It is defined as one one-thousandth of a kilogram, the SI base unit of mass. The symbol for gramme is "g".

History

The gramme was originally defined in 1795 as the mass of one cubic centimeter of water at the melting point of ice. The definition was later refined as part of the metric system.

Usage

The gramme is widely used in many fields, including science, medicine, engineering, and commerce. It is commonly used to measure non-liquid ingredients in cooking and grocery shopping worldwide.

Zénobe Gramme

Zénobe Théophile Gramme (1826–1901) was a Belgian electrical engineer and inventor. He is best known for inventing the Gramme machine, a type of dynamo that produced a steady direct current (DC) and was a significant advancement in the field of electrical engineering.

Early Life

Gramme was born in Jehay-Bodegnée, Belgium. He showed an early interest in mechanics and electricity, which led him to pursue a career in electrical engineering.

Inventions

The most notable invention by Zénobe Gramme is the Gramme machine, which he developed in the 1870s. This dynamo was one of the first to produce a continuous direct current, making it a crucial development for the use of electricity in industrial applications.

Legacy

Gramme's work laid the foundation for modern electrical engineering and the widespread use of electric power. His contributions are commemorated in various ways, including the naming of the Gramme unit of magnetic flux.
