create yourself a number line going

64 32 16 8 4 2 1

and then put the binary number underneath it, e.g.:

Code:
Number line:  64 32 16  8  4  2  1
             ---------------------
Binary:        0  0  1  0  0  0  0
reading across you can see that:

0x64
0x32
1x16
0x8
0x4
0x2
0x1

since the only number you have is 16 the answer is 16 so 0010000 = 16

as csamules says windows calculator will do it for you. stick it in scientific mode and you can convert between binary, hex, octal and decimal
