<p>Do you guys know of any shortcuts to converting from binary to hex?</p>

<p>I’ve been doing it the slow way by identifying the groups of 4 and their respective hex equivalents. To do this, I usually have to look up the table or if I’m not given the table, I have to write it out myself like so:
0000
0001
0010
0011
.
.
.
1111</p>

<p>I don’t like this method as it’s slow and if I write down that table wrong, I’ll get the answer wrong.</p>

<p>You do realize that each binary digit has place value, right?</p>

3

<p>Yes, but I don’t see what that has to do with this.</p>

4

<p>Practice for 20 minutes. You’ll memorize it and it’ll be real quick.</p>

<p>The binary place values are:</p>

<p>8421</p>

<p>So the way to convert is to just add the place values. Examples:</p>

<p>0101 = 4 + 1 = 0x5
1011 = 8 + 2 + 1 = 0xB</p>
