We can convert, quite easily, a hexadecimal value into denary. Remember that binary is base 2 and denary is base 10. As hexadecimal has 16 values for each unit it must be base 16. As such we can use our equation to convert hexadecimal values. Consider F2

(F x 16^1) + (2 x 16^0) = (15 x 16^1) + (2 x 16^0)

= 240 + 2

= 242
