The Hubble weighs about 24000 lbs on Earth. That would be about 11000 kg.
All prefixes scale by powers of ten and so moving the decmal place makes scaling easy.
You can't do that, of course, with ounces and pounds. It is equal to 1000 kg, so you could say the HST weighs 11 metric tons. There is no ambiguity with that as there is between short tons and long tons. Your use of pounds is confusing. You are equating it to kilograms instead of the proper unit of newtons.
