Do you need the exact values? And just out of curiosity: why?

yup. i think i need.Working on something. ;). Wikipedia says LMC is 40% of milky and SMC is 10% of milky.but a scientific paper assumes LMC's as 0.008 while for SMC as 0.004. Things that can't be connected.

Can't grab it. Here is a catalog: http://www.mpa-garching.mpg.de/SDSS/DR4/Data/stellarmet.html but is a bit of work.

metallicity is a complicated issue, and giving just one number (usually Z, but also 12+log(O/H), ...) is very rough. But, here are the standard values for the Magellanic clouds:

LMC: Z~1/2

SMC: Z~1/5

with Z=1 being the solar value. Practically, the values will vary across any given galaxy (the Milky Way also has a metallicity gradient).
