base conversion?

Question

Is there any way I can convert a number from one base to another base, without using a calculator?? ( I know conversion of binary to decimal and vice-versa but I have no idea about the other bases).
I want to do it on paper . Is there any way?? Thanks.

Mr.bz2hcy, can you give an example please???

Answer 1

here's a general way to do it.
Each digit represents a power of the base.
so, divide by the highest power of the base that will fit, and that is the value of the digit. Take the remainder, and divide by the next smallest power of the base - if it doesn't divide into the remainder, then the digit is zero. Keep going, and that will give you each digit you're looking for.

Answer 2

Except for the conversions between base 10 and base e, you are probably stuck with the calculator or pen and pencil. Some base conversions, like from base 2 to base 4, are fairly simple. Any number can be converted from one base to another by log comparison.

♠ hex to decimal: convert 7DE = 7*16^2 +13*16 +14 =2014;
♣ decimal to hex: convert 20140 = 1258*16 +12 =
= 4*16^3 +14*16^2 +10*16^1 +12 = 4EAC;
consecutive dividing by 16 and finding remainders;
