I think you’re thinking of Planck’s Constant, Occam, which is 6.626 x 10^34 Joule-seconds.
The Joule is the SI Unit of energy. It’s the amount of energy required to exert a force of one Newton over a distance of one meter. (The Newton is the SI Unit of force. It’s the force required to accelerate a mass of one kilogram at a rate of one meter per second squared. (The kilogram is the SI Unit of mass. It’s … aw, ferget it.))
The truth, as always, is more complicated than that.
