Hi 2021-10-12 19:50:52@Thad probability unlikely because of N not (likely) a roman number and the arrangement of M in the back, big numbers in the front mostly.

Mergen 2021-10-04 05:29:16Very nice, but a bit limited. Please make the limit more bigger. But other than that, this website gets a VIII/X for me :D.

aipiary from arras 2021-07-23 01:53:10This is a really good tool:It is good but

32767 must be XXXMMDCCXVII(The three X's in front is "upperlined"),

but it says it is MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMDCCXVII.

You must implement something for bigger numbers.

i agree with this. make your numbering system use upperlined and double upperlined numbers such as __M or __MCXVI with the number sys they mentioned your max is now __M__M__M__M__M__M__M__M__M__M__M Ten upperlined "M"s is max due to keeping things tidy but still i m p l i m e n t t h i s

Joyce 2021-07-07 22:36:14What would be in roman numeral in 11,000 - 4300?

Albert 2021-07-06 19:04:21It's a very good app to use

Dale 2021-06-30 20:21:39M = 1,000

_

M = 1,000,000

The line above multiplies it by 1000.

Dale 2021-06-30 20:17:20Why does your converter not include being able to put a line over a roman numeral?

The line above a multiplies it by 1000

which we learned in school.

The line is called a “vinculum”

your converter only goes up to 99,999.

Florian 2021-06-06 11:39:58Theorically, there could be a lot of different ways to write the same number. For example, 49 could be written as :

XLIX (the most conventionnal, using substractive notation),

IL (shortest but not conventionnal, using substractive notation),

XXXXVIIII (largest, using additive notation),

XXXXIX or XLVIIII (intermediate, using both notations).

Also, this converter does not support large number notations such as ↁ (IↃↃ) for five thousands, etc.

Kenny 2021-03-31 12:08:58Pls is their fraction in Roman numerals?

Harley 2021-02-08 03:41:44The Romans and others used the abacus to do their calculations. The Arabic system as demonstrated by the famous Fibonacci was clearly superior for doing calculations. The modern number system ultimately came from the itinerant artisans who traveled from the region of modern Lebanon and Israel to Egypt, to on their monuments. There is a sort of Rune stone figurine that has Egyptian hieroglyphs written on one side and a phonetic letters of a simplified Egyptian letters that represented the same message, but as an alphabet in their native language. That alphabet is the source of all modern alphabets *and* our numbers.

The Indian mathematicians created the zero to clean up the number system and over time the Arabic empire acquired both the numbers and alphabet. The did work to advance complex math like Al Gebra (the way), added to the knowledge accumulated from the Greeks and others as an amassed body of knowledge.

Eventually the knowledge came to Europe through the Spanish after they pushed Muslim rule out of Spain and began to seriously translate the Arabic into Latin where it was shared across Europe.

The rest is history after Bacon established the concept of the repeatable experiment in England. That allowed knowledge to expand based on a growing body of technology shared between members of a growing community who were in pursuit of understanding.

Thus, Roman numeral use fell to headers and the date at the end of a movie.

Charles Boylan2020-12-29 15:00:40

The letter M with a dash above it represents 1 million, eg 1000 x 1000, the dash means x by 1000, just as L with a dash above it means 50,000. and D with a dash above it means 500,000.

i like the facts, and this is completely correct, but you forgt to mention when there are 2 dashes or more, in this situation, with __L = 50,000,000

LRP 2021-01-13 01:24:35Is there a site that instructs on how to do math in roman numerals? I mean like adding a column, subtracting, dividing or doing other forms of math? Is this really all the romans were able to do "write down a number". Seems just a little lame for math. BTW I can convert the numerals to Arabic numbers do the math and convert answer back to roman however I find nothing in the literature indicating they did this or had even gotten to Arabic numbers until after their empire fell.

Tiana 2021-01-06 09:32:33Hi,very useful site. Easy to convert numbers to roman numerals and roman numerals to numbers. Can do my calculations very fast. Thank you for creating such a helpful and useful site.

Spengler 2020-12-14 21:51:43An interesting website, though it has a very conventional approach to Roman Numerals -- the Romans themselves were not quite as strict, nor were many who used them afterwards. I put in MDCCCCIL and it didn't know it, though it was used by a book from an old style publisher. The four "C"s in a row threw the program because that is not conventional, but was done sometimes, and putting an "I" for one before and "L" for fifty would not usually be how one does "49" since it would normally be more the complex XLIX. The rules are not hard and fast, but more conventional versus a little more unusual -- this one uses them as if they were hard and fast. Works though, for that purpose.

which means,there's no Roman numeral conversation in millions, I tried I couldn't get

Well apparently there is a conversion for millions, it just isn't on here. The conversion is _M

zubairuabdullahi 2020-12-03 23:35:03which means,there's no Roman numeral conversation in millions, I tried I couldn't get

hiiii 2020-12-03 18:38:55To Thad, no, it is not a roman numeral. To Didi, MM is 2000. To Dan, there is no zero because nobody has been able to find out what stands for it. Whatever it is, it is not scientifically proven yet.

hiiii 2020-12-03 18:36:13To Mrs. N, VIIX is not a roman numeral. Bigger numbers have to come first unless the first number is 4 or 9. Same goes for you Kbe, IIIVXX is not a roman numeral. i will do 2 more people. To ADRIEL, mdcccxlviii is equal to 1,848. Finally to This is a really good tool, you are right, but 32787 is _X_X_XMMDCCLXXXVII.

hiiii 2020-12-03 18:29:13Hi again. I'm answering comments for you! To Sonu, XXV is 25, and XII is 12. Hope this was helpful

hiiii 2020-12-02 18:34:21This was so fun. For some people though, it is difficult because there is nothing after M. There actually is though. for thousands (and 1M) you have one line over the letters, or one line beside. For example, 5K = _V. It is the same for millions and so on, you just add one line each time you get to M
