    any letters on them, they could be in pico or nana farads.

    Photos? Put something in the pix so we can tell what size they are. Something marked in millimeters or inches, an American penny. Whatever you have.

    ps, most of those numbers are "standard" sizes of capacitance.

    Those look like...DodgyDave is quicker than I am.
    Standard sizes. No multipliers. They are only what the label says, in picofarads.
    What size is the measuring device? Inches? millimeters?
    Might be as low as 50 volt rating or 100 volt rating.

    The caps with underline are rated at 50V/100V; otherwise the rating is 500V according to one source I saw.
