Roman Numerals 1-100: Complete Chart and Converter Guide
On this page

Roman numerals are everywhere: Super Bowl numbers, movie sequels, clock faces, book chapters, monarch names like Elizabeth II. Yet most people can only confidently read up to about XII. This guide fixes that — you’ll learn the seven symbols, the subtractive trick that makes the system click, see the complete 1–100 chart, and get a free Roman numerals converter for instant conversions.

How Roman numerals work: the 7 symbols

The entire system is built from just seven letters:

Symbol Value
I 1
V 5
X 10
L 50
C 100
D 500
M 1,000

For 1–100 you only need the first five: I, V, X, L, C. Write symbols largest to smallest and add: VIII = 8, XXVII = 27.

The subtractive notation trick

Here’s the rule that unlocks everything: a smaller numeral placed before a larger one is subtracted. This keeps numbers compact — instead of writing 40 as XXXX, you write XL (50 − 10 = 40).

There are only six subtractive pairs to learn:

Pair Value How to remember
IV 4 1 before 5
IX 9 1 before 10
XL 40 10 before 50
XC 90 10 before 100
CD 400 100 before 500
CM 900 100 before 1,000

For 1–100 you only need the first four: IV, IX, XL, XC. Three sub-rules keep the system consistent:

  1. Only subtract powers of ten (I, X, C) — never V or L. So 45 is XLV, never VL.
  2. Subtract only from the next one or two larger values — I goes before V or X only; X goes before L or C only.
  3. Never repeat a symbol more than three times — that’s exactly why 4 is IV instead of IIII.

1 I 11 XI 21 XXI 31 XXXI 41 XLI
2 II 12 XII 22 XXII 32 XXXII 42 XLII

8 VIII 18 XVIII 28 XXVIII 38 XXXVIII 48 XLVIII
9 IX 19 XIX 29 XXIX 39 XXXIX 49 XLIX
10 X 20 XX 30 XXX 40 XL 50 L
51–60 61–70 71–80 81–90 91–100
51 LI 61 LXI 71 LXXI 81 LXXXI 91 XCI
52 LII 62 LXII 72 LXXII 82 LXXXII 92 XCII
53 LIII 63 LXIII 73 LXXIII 83 LXXXIII 93 XCIII
54 LIV 64 LXIV 74 LXXIV 84 LXXXIV 94 XCIV
55 LV 65 LXV 75 LXXV 85 LXXXV 95 XCV
56 LVI 66 LXVI 76 LXXVI 86 LXXXVI 96 XCVI
57 LVII 67 LXVII 77 LXXVII 87 LXXXVII 97 XCVII
58 LVIII 68 LXVIII 78 LXXVIII 88 LXXXVIII 98 XCVIII
59 LIX 69 LXIX 79 LXXIX 89 LXXXIX 99 XCIX
60 LX 70 LXX 80 LXXX 90 XC 100 C

Notice the pattern: every decade repeats the same 1–9 endings after its decade marker. Learn one decade and you’ve nearly learned them all.

Worked examples: building numbers step by step

Example 1: 44 → XLIV Break 44 into 40 + 4. Forty is XL (10 before 50). Four is IV (1 before 5). Combine: XLIV.

Example 2: 99 → XCIX Break 99 into 90 + 9. Ninety is XC (10 before 100). Nine is IX (1 before 10). Combine: XCIX.

Example 3: 67 → LXVII Break 67 into 50 + 10 + 7. Fifty is L, ten is X, seven is VII. Combine: LXVII.

Example 4: Reading backwards — MMXXVI = 2026. Beyond 100, the same logic applies: 1,000 + 1,000 + 10 + 10 + 5 + 1.

The general method: take the largest chunk you can, write it down, and repeat with the remainder.

How to convert with an online Roman numerals converter

For homework, tattoos, event dates, or chapter numbering, a converter is faster and error-proof. Here’s how to use our free Roman numerals converter:

  1. Open the converter — no signup, works on any device.
  2. Enter your number (for example, 2026).
  3. Read the result instantly — the tool applies all subtractive rules automatically.
  4. Reverse it just as easily — paste MCMXCIV and get 1994 back, handy for dates on buildings and monuments.

Where you’ll actually meet Roman numerals

  • Clock faces — traditionally IIII instead of IV for 4 (a centuries-old clockmaking convention).
  • Movie sequels and game titles — Rocky II, Super Bowl LX, Final Fantasy VII.
  • Book chapters and outlines — Chapter XII, Appendix IV.
  • Monarchs and popes — Elizabeth II, Henry VIII, John Paul II.
  • Film copyright dates — older movies hide the year in the end credits (MCMXCIV = 1994).
  • Tattoos and wedding dates — always double-check with a converter before the ink.

Frequently asked questions

How do you write 44 in Roman numerals? 44 is XLIV: XL (40, from 50−10) plus IV (4, from 5−1). Break the number into tens and ones, convert each part, and join them.

What are the 7 Roman numeral symbols? I (1), V (5), X (10), L (50), C (100), D (500), M (1,000). For 1–100 you only need I, V, X, L, and C.

Why is 4 written as IV instead of IIII? Subtractive notation (IV = 5−1) is shorter than IIII and became the standard. IIII still survives on some traditional clock faces.

How do I convert Roman numerals back to numbers? Add each symbol’s value left to right, except when a smaller value precedes a larger one — then subtract. So XLIV = (50−10) + (5−1) = 44.
