20971520 Bytes are in 20 MB.
21 bits.
One nibble, or nybble, is equal to four bits.
Because the people who decided to name them bits decided that 8 bits makes up a byte. It is just like asking why is a knife called a knife no real reason.
The subnet mask itself is an IP Address so it is also 32 bits
loosers you stupid suckers
Thirty bits make up the network portion of a class C address. Three bits are borrowed for the subnet mask. There is also a class A and a class B that are comprised of bits.
One byte equals eight bits.

Finishing up with some math, I got somewhere around 1048576 bits in 1 single megabit.
5 bits are necessary to create up to 30 subnets.
1 MB= 1024 KB * 1024 BYTES = 1048576 Bytes as we know 8 bits = 1 byte so 1048576 bytes=1048576*8=8388608 bits. so 1MB=8388608 bits
8 bits = 1byte
