Terminology
Meter is the standard international measure since 1791 based on the decimal system.
The original terminology came from the French National Assembly as a suggestion for the reform of the complicated national system of weights and measures by the Paris Academy of Sciences. In the intervening years, the exact length of the meter was refined.
