# The zero is an o in comments

In a comment, I wrote:

Absolutely 0ms isn't possible with any circuit.

Here, in a question, you can see a slight difference between the zero and the o: 0o. But in a comment you can't: 0-10 second on-time with a potentiometer

Can we please have a font that shows the difference between o and 0 in both questions/answers and comments? It's very important for our users, I believe.

I've read this old answer on meta that states the same. You can see there that this can be workarounded with either $\LaTeX$ or code digits, but I'd say that's overkill for simple things like "0ms".

• The convention that I learned to avoid confusion is to put a space between the value and unit (e.g. 0 ms, or even 0.0 ms). – W5VO Feb 5 '13 at 6:47
• That's possible, but still isn't that neat, is it? – user17592 Feb 5 '13 at 6:49
• OT for here but actually 0 ms would be possible with some circuits in the context of the original question. – PeterJ Feb 5 '13 at 9:52

Very few fonts give an unambiguous distinction between 'o', 'O', and '0'. The only one that I've seen is basically a monospaced font, the same one seen in the edit window and in c0de blocks.
