How do I convert hexadecimal to denary?
Hexadecimal is a base 16 number. This means that it contains 16 numbers in each column instead of 10 like in the decimal number system.
Instead of writing 10 – 15 in the units column (0-15 is 16 numbers) hexadecimal substitutes letters from 10 to 15.
10 = A
11 = B
12 = C
13 = D
14 = E
15 = F
For 1 digit hexadecimal numbers 0 to 9 are the same in hexadecimal as they are in decimal / denary.
Numbers 10 to 15 are converted into letters A to F.
