173₁₀ = 10101101₂
Decimal 173 = 10101101 Binary

Any integer can be written as sum of potencies to the power of 2, known as binary code.

Here’s the proof that 10101101 is the correct result:

1×2^7 + 0x2^6 + 1×2^5 + 0x2^4 + 1×2^3 + 1×2^2 + 0x2^1 + 1×2^0 = 173

Convert 173 to Binary

Now you already know the most important thing:

10101101₁₀ equals 173₂ if unsigned.

If 173 in binary is signed such as with two’s complement, then the binary code has a number of trailing zeroes, e.g. 00010101101 in which the leftmost bit is the sign bit, followed perhaps by more trailing 0’s, and then by magnitude bits.

The reason to have the binary signed is to accommodate for negative numbers, in which case the sign bit is 1 in our example.

Therefore, minus 173 signed using two’s complement, will start with one or more 1’s, but the exact code for -173 decimal depends on the signed number representation system and number of bits available.

Here you can convert binary to decimal.
