Most airsoft RIS rails are the same size. it is safe to assume that an optic, light or otherwise will fit on any Weaver, Picitanny, or 20mm rail.
11 mm dovetail rail

This is not a valid conversion. Square mm is a measure of area. Cubic mm is a measure of volume.
345 mm is a measure of length. A measure of density would have units of mass divided by volume.
Yes, they shoot plastic 6mm bbs
To measure the mm of an item you would need to use a metric ruler. The metric ruler has cm and mm on it.
Anything bigger than a mm.
there is track width (measured from mid rail to mid rail) and track gauge (measured from inside rail to inside rail. As that is the most important size of track, that is normally the distances referenced to. normal distance for track gauge is 1435 mm
no
Airsoft does not have gauges (those are for actual shot-guns) but BB's do come in sizes. The sizes are known in mm (mili-meters) and they range anywhere from .12 to about .48
Any length or distance can be expressed in mm.
NO mm, as that is a measure of length and will NOT compare with teaspoons.
