There are a few units or scales that measure these extreme distances:
Light Years - The distance taken for light to travel in one Earth year (365.24 day)
* Approx. 300,000km/ second * 60 seconds * 60 minutes * 24 hours * 365.24 days
Astronomical Units (AU) - The average distance between the Earth and the Sun
* 93,000,000 miles or 149,668,992 km - Jupiter is about 5.2 AU from the Sun
Parsecs - Based on a formula
* Basically 1 Parsec = 3.26 Light Years or 3.09 × 1013 km
Yes, galaxies can be any size and shape.
It depends on the tear size.
This has no relation to penis measurement. Everyone is different.
If you're talking about the skull only, there is the Cephalic Index, or the ratio of the vertical measurement to the horizontal measurement. -But that's probably not what you are looking for.
The measurement box of cement is used for measuring quantity of aggregates for mixing with cement, when the mortar/concrete is specified in volume. As the volumetric content of a 50 kgs bag of cement is 35 litres, the measurement box of size equal to 35 litres is made. Generally the inner size of measurement box is 40cm x 35cm x 25cm.
Yes, galaxies can be any size and shape.
The space in between galaxies is far larger than the galaxies themselves.
are spiral galaxies are generally older than elliptical

From dwarfs to giants.
A measurement close to true size is referred to as Precision Measurement.
Large and Dwarf.
They are measured in light years. Galaxies are often 100,000 light years across or more.
Galaxies are classified by their shape and size. The main kinds are ellipticals, spirals, irregular and dwarfs.

Nothing whatsoever. The two are not associated.
