| Base | Value |
|---|---|
| Decimal (base 10) | 200 |
| Binary (base 2) | 11001000 |
| Hexadecimal (base 16) | C8 |
| Octal (base 8) | 310 |
How 200 converts to binary
Binary is base 2, so each place is worth twice the one to its right: 1, 2, 4, 8, 16, and so on. Adding up the place values that have a 1 gives back the decimal number:
128 + 64 + 8 = 200
That is why 200 in decimal is 11001000 in binary: it is exactly the set of powers of two that add up to 200. To get the hexadecimal form, group the bits into fours from the right and write each group as one hex digit, which gives C8.
