Roman Numerals

Roman Numerals is an old decimal numeric system which represents the numbers as combinations of the following Latin letters: I, V, X, L, C, D, M (Roman Numerals Symbols). By using combinations of these symbols it is possible to record Roman Numeral Numbers. This system based on 7 Roman Numeral Symbols was invented and used by the Romans starting from the 7th - the 6th century BC and almost till the late Middle Ages. In our times, Roman Numerals are sometimes used for scientific (especially in chemistry, pharmacy, photography, seismology, etc) and some daily purposes (for example, in the names of the monarchs, on the clock face, for page numbering, etc.)

At this website, you can make Roman Numerals Conversion by using our online Roman Numerals Converter, as well as a number of the most commonly used Roman Numerals Charts, including the ones for 1-10, 1-20, 1-100, and 100 - 1000. This Roman Numerals Converter is very simple and user-friendly, and in order to make a fast Roma Numeral Conversion, just enter the number to the box on the right and press 'Convert to Roman' button.

I've recently been shopping for a watch and it appears that all watchmakers, when using roman numerals on the watch face, they always use IIII for the number 4 instead of IV, but they always IX for 9. Does anyone know why this is?

This is awesome. I'm only 5th grade hehe.

(49=XIL right?)

Good information to know

There are some comments that are incorrect. And the start of this only lists half the Roman Numerals.

The list of lower characters are:
: "I" (1), "V" (5), "X" (10), "L" (50), "C" (100), "D" (500), "M" (1000 or 1K).
The list of upper characters, which have a line above the letter (which I can't draw but will represent with ^)
: "V^" (5K), "X^" (10K), "L^" (50K), "C^" (100K), "D^" (500K), and "M^" (1000K or 1 million).
The line above is kind of like an inverted underscore.

Absolutely max 3 characters in a row, and only of "I", "X", "C", "M", "X^", "C^", "M^". The 5x and 10x ones can have 1 before and up 3 after of the 10x that is below it. (IE: IV, VI, VII, VIII, IX, XI, XII for 4, 6, 7, 8, 9, 11, 12)
Thus:
Mary Jane: MCMLII = 1952. ; MCMLCII is not a legal number. The correct would be MCMLXII = 1962.
51A1000: Correct. MDCXVI = 1616.

The 1962 is a tough one to read for some. The "LX" is 60. The "II" is 2. However, one could also read it as "L" = 50, "XII" = 12 and 50 + 12 = 62. :)

The maximum roman number that can be counted is (with ^ representing a line above the character before)
M^M^M^C^M^X^C^MX^CMXCIX = 3,999,999. Breakdown:
(M^M^M^)= 3 Million, (C^M^) = 9 hundred thousand, (X^C^) = 90 thousand, _
(MX^) = 9 thousand, (CM) = 900, (XC) = 90, and (IX) = 9.

There are no legitimate roman numeral for 4 million or above. Most people also don't notice or know that there is no representation of 0 (Zero). This is because 2 thousand years ago people couldn't count what they didn't have. It is why the dewey decimal system goes from 1 to 10 and not 0 to 9.

Very helpful. Thank you

51A1000 2016-09-23 00:15:04

MDCXVI = 1616, Right?

haru 2016-09-05 11:05:36

I did`t know there are many roman numbers.

Merlijn 2016-08-27 19:17:22

9 is IX, because in roman numerals, you never put more than three of the same sign in a row;

I
II
III
IV
V

Putting a sign with lower value in front of another means you substract it.
IV=4
CDIX=409

the sign M can be repeated more than three times, but every M more than 3 gets a stripe above or below it.

Rubaly 2016-08-21 01:35:09

How is 9 IX can u give me a way to study them please
