Default What does mW mean?

I guess its how powerful your laser is, like mine is 95mW.
But what does the mW stand for?

Default Re: What does mW mean?

W is for watt which is a joule/second.
m is for milli or 1/1000.

So your laser is 95 mW which means it is 0.095 watts or in 1 second it puts out .095 joules of energy.

Sometimes people capitalize the m which is wrong because a capital M is for Mega or million, laser pointers dont put out millions of watts.
