Starting at the right with the "ones", the value of each successive place doubles. So: 1, 2, 4, 8, 16 etc. The value of the place is either 0 x that number or 1 x that number. You figure out the value of each place and add them up.

So you have:

0 x 1 =0

0 x 2 =0

1 x 4 =4

1 x 8 =8

1 x 16 =16

0 x 32 =0

1 x 64 =64

1 x 128 =128

1 x 256 =256

0 x 512 =0

0 x 1024 =0

1 x 2048 =2048

0 x 4096 =0

1 x 8192=8192

11110000 (base2)

= 1 * 2^7 + 1 * 2^6 + 1 * 2^5 + 1 * 2^4 + 0 * 2^3 + 0 * 2^2 + 0 * 2^1 + 0 * 2^0 (base 10)

= 2^7 + 2^6 + 2^5 + 2^4

= 128 + 64 + 32 + 16

= 240 (base 10)

to convert 10101111 start from least significant digit and multiply each digit of binary number by 2^(n){where n=0,1,2,3,4.....} and add the number calculated. The number obtained after addition is the equivalent decimal number. ex.- for 10101111 1*(2^7)+0*(2^6)+1*(2^5)+0*(2^4)+1*(2^3)+1*(2^2)+1*(2^1)+1*(2^0) = 175
