The specific gravity of PURE methanol is .792 at 68 degrees. That of course changes if there are any additives at all in it. A simple hydrometer is cheap and effective (Buy the 6" version, easier to work with) and you can use it in the same 100 ml cylinder you use to cc your heads.

can it be used to check % of ethanol? Say 78%-85%?
Saw one at McMaster-Carr, $16= .650-1 spec. gravity.
Thanks, Don

Yes! There are charts available to read percentage of methanol at a given temperature based on specific gravity. All you would need is the exact temp and sg and the chart will give you percentage assuming water is the dilutant. If you have something else other than water all bets are off unless you know the chemical makeup of what it is. Make sense? PM your email addy and I'll get you some info tomorrow when I hit the office.

EDIT Damn - just saw you said ethanol. I do that too so I can get that info for you if you want.
