I searched Google, and even asked on a few W3 mailing lists. No dice.

Every site I found on Google has said "divide pixels by 16 to get the size in em for images" but that's wrong. Dividing by 16 makes the images smaller than they really are.

So, does anyone know the actual number to divde pixels by to get the number in em?

Having em's in images allows them to be scalable in Firefox and Internet Explorer (Opera does this by default) when making text larger or smaller in the browser.

Umm... Could you please explain ems?

OK, I still don't know what ems are but I found this on Google:

Y = The number of pixels
X = The number of ems

Xem = 0.083333 * Ypx for 75% font size
Xem = 0.0715 * Ypx for 87.5% font size
Xem = 0.0625 * Ypx for 100% font size

Does that make sense to you?

Number of em times Number of px, makes no sense to me (really sucks at math)
the * means 'multiply' that's all I know

About your question on what em's are:

They are a unit of mesure for text/image size.

1em is about "average" text size in the browser, or about 10-12px text size.

0.9em is 1 fraction of a full unite of mesure. So 0.9em is slightly smaller than 1em.

Does any of that make sense?

Here are some definitions on google: http://www.google.com/search?hl=en&l...en&q=define:em

OK:

1em = 1px * 0.083333 (for 75% font size)
1em = 1px * 0.0715 (for 87.5% font size)
1em = 1px * 0.0625 (for 100% font size)

In other words:

1em = 0.083333px (for 75% font size)
1em = 0.0715px (for 87.5% font size)
1em = 0.0625px (for 100% font size)

If this seems way off or doesn't make sense to you, sorry, I found it here:
