Hi,

Well if you have windows you can use your calculator under the bureau accessories. It has the possibilty to switch between binary, decimal and hexadecimal. So you can easily convert using that.

You can also try looking for tools on the net but since the calculator can do it there is no need to look for it I believe.

The theory behind the conversion is rather simple. For instance

0 (hex) = 0000 (bin) = 0 (dec)
1 (hex) = 0001 (bin) = 2^0 = 1(dec)
2 (hex) = 0010 (bin) = 2^1 = 2(dec)
3 (hex) = 0011 (bin) = 2^0+2^1 = 1+2 = 3 (dec)
|
|
F (hex) = 1111 (bin) = 2^3+2^2+2^1+2^0= 8+4+2+1 =15(dec)

You can also translate directly for instance: 28 HEXADECIMAL to DECIMAL

= 2* 16^1 + 8* 16^0 = 32 + 8 =40

I hope this solves your problem.
