I guess to add to that, if you want to convert it to measure it, what do you want to know about it?

A. Peak value
B. Peak-to-Peak
C. Average
D. RMS

It would be helpful to know what the frequency of your AC is.
If it's 47Hz to 63Hz (typical range for mains power) then you'll need larger filter caps than for higher frequencies.

A precision rectifier will convert the AC to rippled DC.
You need to define what you mean by "nice".

Since the AC magnitude is low first you can use a voltage multiplier [Cascade connection of voltage doublers]circuit to convert this low magnitude AC into DC.
Google voltage doubler circuit.

A voltage doubler circuit won't work for 0.24v which is below a diode drop.

The, "Thanks" is for saving me the time it would take to type that answer.

This is beginning to look like a drive-by question.
