There are two measurement systems used in the world today: the imperial system (also known as the English system) and the metric system.

The imperial system was developed in England hundreds of years ago and was brought to the the United States by the colonists. The metric system is the accepted measurement system used in most countries of the world. It is a system based on multiples of 10. The metric system was developed in France around 1790 and has been revised several times. Its official name today is the International System of Units or SI Units for short.

Both systems have come a long way since their conception. Here are some noteworthy facts about both, which may have been "lost" in history, but are still worth mentioning today.

3)  Fraction Bar

The Romans did not use numerals to indicate fractions but instead used words to indicate parts of a whole. It wasn't until later in h [ ... ]
