There is one thing basically wrong with your question; manufacturers' claimed horsepower numbers don't make any thrust.
Not even one ounce; not a gram in fact...
...BTW in order to avoid confusion, gram is unit for mass, not a force unit. In the SI system Newton is the force unit and in Imperial units lbf is often used :-)!
Red,
Yes, a gram is a unit of mass, as is a kilogram.
But it is customary to use kilograms to describe thrust of jet engines, like kilo-Newtons are used, as it is to amount torque in kg-meters and not only in Newton meters.
A force of 1 Newton will accelerate a mass of 1 kg at 1 meter per second squared...
