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.
