The metric system is used today throughout the global scientific community, so why haven't all countries adopted it?

A metric system is any one of the systems of measurement introduced to France in the 1790s. It uses units such as meter, liter, and gram to measure length, liquid volume, and mass.

It was made compulsory by France in 1840. Today, it is the system of measurement throughout the global scientific community. So why do some countries still use imperial measurements?

That is a tricky complicated question to answer. In previous years, different countries and even different regions had their own systems of measurements.

At the time, this wasn't problematic but as the world became more connected issues started to arise. It soon became important and necessary for some standard units of measurement to be developed.

Several scientists at the time proposed standardized units of measurements but it wasn't until the 1790s that such a system really came about. In the midst of the French revolution, the national assembly of France requested that the French Academy of Sciences make a standard for weights and measures.

The new system would consist of measurements derived by nature making them more logical. By the mid-1790s the meter and the kilogram were established. What happened next? You have to watch the video to find out.
