"Size"? One gigameter is one thousandth of a terameter.
Nothing
Yes it is bigger than a meter
One terametre is equal to 1,000,000,000,000 metres. 100 micrometres is equal to 0.000001 metres, or one millionth of a metre.Therefore, expressed in scientific form, 100 micrometres is equal to 1 x 10-16 terametres.
A kilometer (1000 meters). Larger SI prefixes are possible, but are not normally used in practice (megameter, gigameter, terameter, etc.). In astronomy, three non-SI units, all larger than a meter, are often used: the astronomical unit (the average distance from Sun to Earth), the light-year (the distance light travels in a year), and the parsec (the distance at which an object, viewed from Earth, would have a parallax of 1 arc-second).
1 terameter is 1e+10 hectometers.
There are 1,000,000,000 kilometers in a terameter.

one million meters, or one thousand kilometers.One megametre is equal to 1,000,000 metres.
It's 999,999,999,999 meters larger.
1 terameter = 3.2808399 x 10e12 feet

1 terameter is 1e+21 nanometers.
Look at the Wikipedia article "Metric prefix". Please note that it is not customary to use units larger than kilometer.
A tetrameter is not a unit of length - it is a unit of rhythm. Perhaps you are mistaking this for a terameter, which indeed is a unit of length, equal to 1,000,000,000 metres.
