The best way to understood how to convert binary numbers is to take a look at an example.

For example convert decibel 172 to binary

step 1, write the binary chart

128 64 32 16 8 4 2 1

Then we keep asking the questions,

Can we subtract 128 from the 172?

If yes, put 1 under 128, if no, put 0. Here we put 1.

The reminder is now 172-128=44.

We keep asking.

Can we subtract 64 rom 44? no, put 0 under 64.

Can we subtract 32 from 44? yes, put 1 under 32.

The reminder is now 44-32=12.

Can we subtract 16 from 12? no, put 0 under 16.

Can we subtract 8 fom 12? yes, put 1 under 8.

The reminder is now 12-8=4.

Can we subtract 4 from 4? yes, put 1 under 4.

The reminder is now 4-4=0.

Can we subtract 2 from 0? no, put 0 under 2.

Can we subtract 1 from 0? no, put 0 under 1.

Finally, we get 10101100

128 64 32 16 8 4 2 1

172 1 0 1 0 1 1 0 0

172-128=44-32=12-8=4-4=0

172=10101100
