I agree with abdulla
You can only fit the roman numeral 3 times.

Akis 2024-02-10 19:11:14

Great tool!

CW 2024-01-17 04:20:59

Great, best converter!!! of all types...

DJV 2023-12-29 18:35:08

Why does "VC" return "Invalid"? I don't see a rule forbidding this construction, and it is analogous to "XL", which yields 40.

Somto 2023-11-26 16:28:40

You really helped me with my assessment

Jason 2023-11-08 11:22:42

This is very helpful. I have 9 pages of Roman Numeral conversions for homework and thankfully found this site!

Doug 2022-10-08 22:32:13

Wonderful converter.
I have a Scottish publication date of MCMXXV99. What does the 99 indicate - 9 September 1925 ??

Harvey Specter 2022-10-01 07:52:41

XXIV.I.MMIII is how you would write that.

ZaZA B. Wolobah 2022-09-15 02:30:30

This was very educative for me,I learn some new things that I never learn before

Sayed-Afghani 2022-09-07 09:39:25

We can't repeat (M, X, |, or V) more than 3

Sybil Sidebototm 2022-08-07 03:59:27

Generally speaking very Good to know such Roman Numbers especially as time and infinity we are drawing closer climate change and numbers of all kinds Maths and time combine Eternity! Planets forces of life and Space high far away! BC-AD tIme in the Creators hands.

Ryan 2022-07-30 15:55:48

This is going well, but 99999 is not [M repeated 99 times]CMXCIX, It can just be [X with a dash][C with a dash]M[X with a dash]CMXCIX.
Roman numerals can't be repeated more than 3 times.
Other than that, it deserves a VIII out of X! (8 out of 10)

SoulWatcher 2022-07-28 11:58:16

I can read Roman Numerals but sometimes I get messy with the rules because I don’t know the rules I thought I did but I don’t. Not fully. Such as the number 49. I thought take L = 50 and l = 1
And say lL I don’t know why this is wrong. I can write it this way as well.XLIX. Why is the layer the inky right way? What rule am I missing that I can’t seem to find anywhere? Cheers

Rob 2022-07-23 06:33:47

Seems like 490 should be XD, but the correct conversion here is CDXC. Hmm. And 990 should similarly be XM, but the correct answer here is CMXC. This must violate rules of conservation, no? Why would one use four numerals when one could use two? Please clarify. Thanks.

This helped me a lot shout out to the person who created this website DUBS IN CHAT

Oliver 2022-07-13 14:55:12

for 4000 and over we need I V X L C D and M with a dash over it for example 15364 should be X-V-CCCLXIV instead of MMMMMMMMMMMMMMMCCCLXIV

This is very helpful, thank you. Whoever made this site deserves a reward- like a lifetime supply of their favorite thing or something.

DCCCCL is not a valid Roman numeral

Abdullah 2022-06-25 14:50:13

4000 is not = MMMM
A number can't be repeated 3 times in a row

An error on posting Anonymous - 2022-05-11 02:19:34:
The posting listed "...VI=4, V=5, VI=6..."
Seems to be merely a typo. We know IV=4.

Speaking of the number four: my Latin professor said "IIII" was in common usage, just as was the language we refer to as Vulgar Latin ("vulgar," meaning "of the common people" as opposed to Classical Latin, used by scholarly, educated, elite citizenry).

Fikri 2022-05-28 00:48:16

The Roman numeral ll is not a valid representation for number one hundred (the correct Roman numeral is C)

Anonymous 2022-05-11 02:26:17

Here are some more tips and tricks.
If the bigger number comes first you add. For example VI is 6 because 5 + 1 = 6
But if the lower number comes first you subtract. But you subtract the bigger number to the smaller number. For example IV is four because 5 - 1 = 4. You don't do 1 - 5 = -4
The same rule applies to bigger numbers like 40 and 90. 40 would be XL not XXXX because 50 - 10 = 40 and XC is 90 and not LXXXX because 100 - 10 = 90

Anonymous 2022-05-11 02:19:34

This might help you.
I = 1 II = 2 III = 3 VI = 4 V = 5 VI = 6 VII = 7 VIII = 8
IX = 9 X = 10
L = 50 C = 100 D = 500 M = 1000
The line above the number means to multiply by 1000 so V with a line above it would be 5,000 and M with a line above it would be 1000000
