Depends. Light years if finding the diameter of a galaxy, kilometre for an earth size planet, metre for the turning circle of a car, centimetre for a car tyre, micrometre for a precision screw, femtometre for a atom.
Add to that, the precision that you want/need will influence your choice.

What mathematical equation describes how to measure the distance from earth to the moon using earths diameter as a unit of measure?
The mathematical equation which describes how to measure the distance from Earth to the moon using Earth's diameter as a unit of measure is d = Dcot(p/2)/2 Where d is the distance from Earth to the moon, D is the diameter of the Earth and p is the angle of parallax subtended at moon by the diameter of the Earth.
What metric unit of measure would you measure a bacterium?
You should clarify what you want to measure about it: its diameter, mass, weight, color, etc. If you want to measure its diameter, that would usually be specified in microns (= micrometers).
What metric unit would you use measure the diameter of a pencil lead?
Millimeters.
How many meters is equal to a diameter?
A meter is a unit of measure, and a diameter is the longest linear distance from one point on a circle to another. You cannot convert from one unit to another. If you know other information about a particular circle, however, you can find the diameter's length in meters, but this value can change depending on the circle.
