Add together the individual numerals (M = 1000, D = 500, C = 100, L = 50, X = 10, V = 5, I = 1) unless a smaller numeral precedes a larger one in which case subtract it from the larger one.
→ MCDLXXII = 1000 + (-100 + 500) + 50 + 10 + 10 + 1 + 1 = 1472
M represents 1000, D is 500, L is 50 and C is 100. This would convert to 1472.
