When written as a binary number, the decimal number 63 is: 1 1 1 1 1 1
"Ordinary" numbers are on base 10 (="decimal"). Binary only has 2 digits. 0 and 1 (representing "on" or "off" in some circuits). So "conversion" is how to represent an number in one to how it appears in the other. So 10 (binary) means 1x21 + 0x20 , which is 2. Decimal to binary effectively means representing an ordinary ("decimal") number in binary form. So 10 (decimal) is broken up into powers of 2 as 8+2 = 1x23 + 0x22 + 1x21 + 0x20 which is 1010 (binary).
