The English system
Full Answer Section
The last attempt to officially move to the metric system in the United States was in 1975. However, this attempt was met with strong opposition from Congress and the public, and it was ultimately abandoned.
The use of English measurement units can put U.S. companies at a disadvantage when competing on international contracts, as many countries use the metric system. This can lead to confusion and misunderstandings, and it can make it more difficult for U.S. companies to compete.
Software has helped to solve the challenge of using different measurement systems by providing tools that can convert between units. This makes it easier for businesses and individuals to work with both English and metric units.
Some examples of engineering software that resolves this challenge include:
- Autodesk AutoCAD: AutoCAD is a CAD software program that allows users to create and edit 2D and 3D drawings. It includes a unit converter that can convert between English and metric units.
- SolidWorks: SolidWorks is another CAD software program that allows users to create and edit 2D and 3D drawings. It also includes a unit converter that can convert between English and metric units.
- Matlab: Matlab is a numerical computing software program that is often used in engineering and scientific applications. It includes a unit conversion function that can convert between English and metric units.
Sample Answer
The United States still uses the English system for a number of reasons, including:
- Historical inertia: The English system was the system of measurement used in the United States when it was founded, and it has been in use for centuries. This inertia has made it difficult to change to the metric system.
- Cost: Switching to the metric system would be expensive, as it would require businesses and government agencies to replace all of their measuring equipment and signage.
- Public opposition: There is some public opposition to switching to the metric system, as many people are familiar with the English system and are reluctant to change.
