what weight is light?

Light can be thought of as both a wave and a particle.  Light particles (quanta) are called photons, and these are massless.  However, they do have a momentum.\nFor more information on photons see:\nhttp://en.wikipedia.org/wiki/Photon

Ok, let's set this straight. Weight is a measure of the force exerted on an object by a gravitational field. It is measured in NEWTONS. Most people are getting this mixed up with mass, which can be measured in metric tons and doesn't change from one gravitational field to another. The weight of the lead on the moon is only 166 Newtons.

same mass, same weight

Light doesn't have a rest mass, that is an inherent mass that it would have it it were at rest relative to you, but it does have a mass equivalence due to its energy. \n\nE=MC^2 gives the relationship between mass and energy, so you can rearrange this to M=E/C^2 to find the mass equivalence of a given amount of light.  The energy of light can be calculated a number of ways, and then this number can be plugged into the mass-energy equation.  Needless to say, it takes a whole lot of light to add up to a significant amount of mass.\n\nEdit:  Sorry, Mathematician, you're incorrect.  Light does have mass and it can be calculated using the mass energy equivalence.  Your argument is basically circular since you're using the definition of light not having a *rest*\n mass to say that it has no momentum, and the statement that it has no momentum to claim that it therefore has no mass.  You're right in that it has no rest mass, but that's not the only kind of mass there is.  If you've ever seen a radiometer work you've seen direct evidence of the momentum of light.

Weight can be determined by mass and the pull of gravity exerted on an object. But mass is not an indication of weight. Mass is presumed to be constant through varying gravities while weight fluctuates because it is proportional to both of these variables.

Nope, the magnetic information (not electronic!) doesn't weigh anything, it's all related to the orientation of the "magnetic moment" (up or down) of the atoms i.e. the way atoms are turning (to make it simple). they're not heavier if they turn in one sense than if they does in the other

25 lbs\nThe distinction between mass and weight becomes obvious when we move away from the earth's surface. For example, on the surface of the Moon gravity is only about one sixth as strong as on the surface of the earth. A one kilogram mass is still a one kilogram mass – mass is an intrinsic property of the object. However, the weight of the object – the downwards force due to gravity – is only one sixth of what it is at the surface of the earth; that is, only one sixth of what we would expect one kilogram to weigh.

Great weight, even can have a few more pounds. Dont worry at all, your at a very healthy weight for your height .=)

light (photon) has no mass... but with is super super great speed, there is an associated kinetic energy (moving) and also momentum (continuously moving)..\nrecall that KE and momentum require mass but with light, no mass....\nuse relativistic equations for relativistic speeds...

The UFC currently uses five weight classes:\n\n    * Lightweight: 146 - 155 lb (66 - 70 kg)\n    * Welterweight: 156 - 170 lb (70 - 77 kg)\n    * Middleweight: 171 - 185 lb (77 - 84 kg)\n    * Light Heavyweight: 186 - 205 lb (84 - 93 kg)\n    * Heavyweight: 206 - 265 lb (93 - 120 kg)\n\nIn addition, there are four other weight classes specified in the Unified Rules which the UFC does not use: Flyweight (125 lb and under), Bantamweight (126-135 lb), Featherweight (136-145 lb), and Super Heavyweight (265 lb and above).
