Converting Hexadecimal Numbers to Decimals
If you prefer to use decimal numbers instead of hexadecimal
numbers, you can convert them with the chart below.
Just read down in the column for the first digit of the hexadecimal
value and across in the row for the second digit. The decimal value
that corresponds to your hexadecimal number is at the intersection
of the column beginning with the hexadecimal number’s first digit
and the row beginning with the hexadecimal number’s second
digit.
For example, to find the decimal equivalent of the hexadecimal
number 5A, find where column 5 intersects row A. There you will
find the hexadecimal’s equivalent, decimal 90.
