Hey I ain't a computer geek but still... Now suppose the number you wanna convert is like 1011. 1. Move from right to left. 2. The rightmost bit is '1'. So you do 1 x (2 raised to zero (zeroth bit)) =1 3. The next bit is '1'. So you do (previous answer) + 1 x (2 raised to one (first bit)) = 1+2=3 4. The next bit is '0'. So you do (previous answer) + 0 x (2 raised to two (second bit)) = 3+0=3 5. The next bit is '1'. So you do (previous answer) + 1 x (2 raised to three (third bit)) = 3+8=11 So the number 1011 in decimal is 11... You should ask such questions in Yahoo answers. This a place to 'discuss' things buddy... Take care...

Hi vkprincedark, He want to know the steps I think. We could directly convert a binary to decimal without much effort. But step by step procedure is there when we study something in College/School. Regards, Reyas MCTS

Hi there. Sorry if I am too late. I also have trouble to comprehend how to convert binary to decimal and vice versa as they did not teach us well here. Fortunately I found a really useful video on Youtube which shows how to do so. The video shows a fast process to do the conversions and it does work. I tried to use the process mentionned in the video and recreate them on the calculate and it showed the same results. Anyway enough talking, here the video http://www.youtube.com/watch?v=hlV7dMinHFc . Hope that it helps.
