Ok, this may seem long, but, it's best you get the whole spiel from me and not off the street and only get the whole story...
Hexadecimal (or hex) is just a different way of counting numbers.
Normally, people count and do math in decimal (or base ten). It is called base ten because there are ten possible numbers in each digit position. Like here 295?23.
In the ? slot, a 0, 1, 2, 3, 4, 5, 6, 7, 8, or a 9 could be there. That's ten numbers.
Hexadecimal is simply base sixteen. Which means that in each digit position, 16 numbers are possible.
This is how to count in HEXADECIMAL
0 1 2 3 4 5 6 7 8 9 0 A B C D E F 10 11 12 13 14 15 16 17 18 19 20 2A 2B 2C 2D 2E 2F 30 31 32
In hex, they have 6 new numbers (Even though to us they're letters). The A, B, C, D, E, & F.
For all intensive purposes, A = 10 B = 11 C = 12 D = 13 E = 14 F = 15
This is just the concept of what hex is. There is more to explain. But, I can show you how to convert from decimal to hexadecimal very easily (by just using a calculator)
Now, converting from decimal to hexadecimal can be done by hand, but, it takes a little bit of time, and I'd have to refresh my memory on how to teach you correctly. So, here's the quick way...
Load your calculator program on your computer.
It should be at c:\windows\calc.exe
Now, go to view at the top, and select scientific.
See the differnet choices below the readout. They go "Hex Dec Oct Bin"
Make sure Dec is selected.
Now enter a number on the calculator.
After you have entered it, click Hex.
Your original number has now been converted to Hexadecimal.
You can do the exact reverse of these steps to go from hex to dec. Just make sure hex is selected in the first place and then click dec.
Just to make sure you're doing it right try to convert 3424 from decimal to hexadecimal.
If you got D60 you did it right. Congradulations.
