Roman Numerals 1 to 1000
One thousand is M — a single letter — and everything below it is assembled from the same seven symbols. This page gives the complete first hundred, then anchor tables for the rest of the thousand: every ten up to 200, every fifty beyond. With the anchors and the unit pattern, you can build any number from 1 to 1000 without a lookup.

100–500, anchors
| Number | Roman | Number | Roman |
|---|---|---|---|
| 100 | C | 110 | CX |
| 120 | CXX | 130 | CXXX |
| 140 | CXL | 150 | CL |
| 160 | CLX | 170 | CLXX |

| 200 | CC | 250 | CCL |
| 300 | CCC | 350 | CCCL |
| 400 | CD | 450 | CDL |
| 500 | D |
The hundreds are where CD (400) earns its place: 400 is CD, never CCCC, and 500 is D. Between anchors, add the tens and units from the first-hundred table — 273 is CCLXXIII: CC (200) + LXX (70) + III (3).
500–1000, anchors
| Number | Roman | Number | Roman |
|---|---|---|---|
| 500 | D | 550 | DL |
| 600 | DC | 650 | DCL |
| 700 | DCC | 750 | DCCL |
| 800 | DCCC | 850 | DCCCL |
| 900 | CM | 950 | CML |
| 990 | CMXC | 999 | CMXCIX |
| 1000 | M |
The last stretch hides the most famous numeral in the range: 999 is CMXCIX — three subtractive pairs in a row (CM + XC + IX). And 1000 itself is simply M.
Build any number in the thousand
Take the number apart by place value, convert each place from the tables above, and join the pieces: 786 → DCC (700) + LXXX (80) + VI (6) → DCCLXXXVI. That is all the converter does — it just does it instantly and shows the same breakdown. Years in the first thousand of any millennium follow the same rule; for modern years see the year-by-year pages, 1950–2029.
Frequently asked questions
What is 1000 in Roman numerals?
M. It is the largest of the seven base symbols, and it may repeat up to three times — which is what sets the standard maximum at 3999 (MMMCMXCIX).
What is 500 in Roman numerals?
D. Numbers just below it show the subtractive pattern at its clearest: 490 is CDXC and 499 is CDXCIX.
Why aren't all 1000 numbers listed?
A thousand-row table is a wall nobody reads. The complete first hundred plus anchors every ten and fifty cover the full pattern — every other number is an anchor plus a piece from the first-hundred table, as the worked example above shows. For one specific number, the converter is faster than any table.
