The first digit on the right is the one's place. Take whatever number is in that position, and multiply it by one. The next digit, second from the right, is the sixteen's place. Take whatever numer is that position, and multiply it by 16. The next digit, thrid from the right, is the 256's place. (256 = 16^2.) Take whatever number is in that position, and multiply it by 16. The next digit, fourth from the right, is the 4096's place (4096 = 16^3.) Take whatever number is in that position, and multiply it by 4096. Add the result of all those multiplications, and you have the number in decimal. - Warren
 here what i have for Hex 30500000 => Dec = 1052672 (16^3 + 16^5= 1052672) my result seem doesn't right ! I confuse, would you give a example by number instead by words? Don't need to be exacted those hex number above, any number would fine with me, i will follow from there and try to undestand. Again thanks for your explaination.
