Why did Joseph Louis Lagrange invent the English System?

Answer 1

Lagrange did not invent the English System. He worked, with the French Commission for the reform of weights and measures on the International System of Weights and Measures. That is an International System and, although the majority of the world now uses it, the English cannot lay claim to it.

Answer 2

Joseph Louis Lagrange did not invent the English system of units. The English system of units (also known as the imperial system) has roots that go back centuries and evolved over time. Lagrange was a prominent mathematician and physicist who made significant contributions to many areas of mathematics and science, but he did not have a direct role in the development of the English system of units.
