I have an exam tomorrow for an Intro to Networking class and we're going
over binary conversion. Thanks.

Real easy actually; each digit in hex represents 4 binary digits.

For example F in hex is equal to 15 decimal which is 1111 in binary.

So if we go up the scale from 0 to F in hex we will get:

HEX BINARY DECIMAL
0 0000 0
1 0001 1
2 0010 2
3 0011 3
4 0100 4
5 0101 5
6 0110 6
7 0111 7
8 1000 8
9 1001 9
A 1010 10
B 1011 11
C 1100 12
D 1101 13
E 1110 14
F 1111 15

Finally lets convert a multidigit hex to binary

FA72 hex would equal 1111101001110010

F = 1111
A = 1010
7 = 0111
2 = 0010

6 = 0110
7 = 0111
8 = 1000
9 = 1001
A = 1010
B = 1011

Isn't there a mathematical computation that I can perform to get those
numbers from hex to bin? Like with bin to hex you multiply each bin # by
2^1, 2^2, so forth and the 0 places, you just disregard those and add the
sum of all the bin 1s and from there you convert those #s to hex.

It's called MEMORIZATION.

Unless you have 16 toes.
