it depends how big we're talking
id say generally when i hit 100 of a unit i usually start using the next biggest one
e.g. 1-100cm, 1-100m, .1-100km
as long as the resultant measurement is easily understandable enough (like, if you say .000004km or 56,000cm people are going to have to convert in their heads) it should be ok
that would depend on the size of the object. for eg the length of the golden gate bridge and the length of a knife would take 2 completely different units.
That would be distance.
That would be distance.

To measure the solid volume of an irregular object, you can use a graduated cylinder filled with water. By submerging the irregular object in the water, you can measure the change in water level, which corresponds to the object's volume. Alternatively, you could use a displacement method with a volumetric flask or a beaker, ensuring that the object is fully submerged for an accurate measurement.
Firstly, it depends what you are measuring, and second it depends what you mean by large! If you wanted the volume of a packing crate you could use cubic metres. (Or cubic yards or feet in Imperial.) For the volume of a planet, cubic miles or kilometres would be more sensible. If you wanted the mass you could use kilograms or tonnes (or tons).
You would use a ruler or measuring tape to measure the length of an object. Place the edge of the ruler or tape at one end of the object and note the measurement where the object ends. Make sure to read the measurement carefully to get an accurate length.
Which of the following would be an appropriate scale of measurement for a small scale map showing a large region :
Liters or gallons would be appropriate units of measurement for measuring the volume of a large pot.
You would have to put mercury in very low temperatures until it was a solid.
That object would have to be a solid using the lengthxwidthxheight.
A scale that measures weight would give a different measurement in space than on earth for the same object.
