For example, most engineers I know will pronounce "18, 19, 1A, 1B, 1C" as "eighteen, nineteen, one-A, one-B, one-C".
Why not incorporate the hexadecimal digits A, B, C, D, E, F into the same number pronunciation scheme as 0 through 9?
Here's how it would work. Let's write out the hex digits as follows:
Now we can combine them with existing number parts, like -teen or twenty-.
Also, B5 is "beety-five", DA is "deety-ay", FF is "effty-eff", E7C is "ee hundred seventy-cee", etc.
One drawback is that "ay" sounds a lot like "eight". So 80 (eighty) and A0 (ayty) are a problem. But we already have some close sound-alikes, such as "seventy" and "seventeen".
Now I just have to remember to use this in meetings. I'm sure to get some funny looks!
