Roman Numerals
I = 1
C = 100
V = 5
D = 500
X = 10
M = 1000
L = 50
You can use a roman numerals chart or conversion table to lookup roman numerals or you can easily learn how to calculate them yourself with a few simple rules.
How to Translate Roman Numerals
If smaller numbers follow larger numbers, the numbers are added. If a smaller number precedes a larger number, the smaller number is subtracted from the larger. For example, if you want to say 1,100 in Roman Numerals, you would say M for 1000 and then put a C after it for 100; in other words 1,100=MC in Roman Numerals.
Some more examples:
VIII = 5+3 = 8
IX = 10-1 = 9
XL = 50-10 = 40
XC = 100-10 = 90
MCMLXXXIV = 1000+(1000-100)+50+30+(5-1) = 1984
