numere-romane.ro aims to provide users a reliable online tool of working with the Roman numerals, offering not only the end result but also explaining all the steps to be taken in order to get to the end result, giving the users also the tools to learn by themselves.

Why this site?

In 2010, September, I wrote a short article about Roman numerals in the "known-facts" section of haios.ro website. In that article I was trying to explain users how to write numbers using Roman numerals and what are the simple steps of converting an Arabic number to a Roman numeral. It wasn't difficult to notice that quite soon this subject became popular among the site visitors and started to gather increasingly more questions in the form of comments left on the article page, in which I was mainly requested to convert certain numbers to their Roman numerals equivalent.

Here's a link to this article on Roman numerals (in Romanian language though): Roman numerals .

I was more than happy to see that people are really interested in this subject, perhaps some of them having to prepare their required homework for school, others maybe out of curiosity. Whatever the reason, it's a good thing to learn something new and useful every day (your knowledge is one of your biggest assets). So I answered each question that I got from haios.ro site visitors, making all the requested conversions, and not only on that page of the article, under the "known-facts" section, but also on other new pages that I had created in the meantime under the "tests & quizzes" section of the haios.ro site (teste.haios.ro), all on "Roman numerals" topic.

From here to the idea of creating a brand new website to automatically perform the conversion algorithm of the Arabic numbers into Roman numerals, with explanations, was not a long way: online converter of Hindu-Arabic numbers, write them in Roman numerals on: numere-romane.ro .

Why learning on how to write numbers with Roman numerals

Because it's more complicated and less efficient than the ordinary writing, the one using the Arabic numbers! Not everyone can do it. Almost everyone knows how to write numbers down, for example the year of a date of birth: 1996, 2000, 1999, 1997, 1998, 2007, etc.. But just a few know what MCMXCVI means (1996). Would you like to be cool? Learn how to write numbers by using the Roman numerals.

Writing numbers in Roman numerals is still quite used in certain environments, especially when writing dates, but not only, so it is not a bad idea to understand the reading rules.

The conversion of Arabic numbers to the Roman numerals and vice-versa also involves some logic, which in this case can be a fun little challenge for someone willing to do it.
