If you mean a 'spirit level' then when the line is in the center of the bubble then the object being measured is horizontal to the ground.
The micrometer is a precision measuring instrument, used by engineers. Each revolution of the rachet moves the spindle face 0.5mm towards the anvil face.
Ensure the surface to be tested, and the level itself, are clean so bits of swarf etc don't prop the level's end up and give false readings. Ensure the alignment of the level is true along the direction to be tested. Read the level then rotate it 180º to obviate or show any errors in the level.
electric vibrator!
Civil engineers do use jackhammers to break-up old roads and put down new ones.

No. It isnt.

I don't a clue wat precision means sorry ppl

The length of time a star burns depends on its temperature and mass. It's certainly not possible to calculate this to the level of precision of seconds, and it's difficult to do so to the level of precision of millennia.
A Starrett precision level is really no different than any other bubble type level it is just made with far more precision and so can give far more "precise" results.If you are using the Master Precision level you need to be careful not to hold onto the level too long, it is precise enough the heat from your hand can effect the measurement.A typical bubble level may have two or four lines on the vial and you just center the bubble so you are actually looking for the location of the ends of the bubble relative to the line(s).The Starrett precision level, Models # 98, has one major line and 6 lesser lines that are accurately marked on the each end of the vial.This level is adjustable and Starrett suggests any very flat surface be used and a "reading" taken with the level oriented in one direction and then turning the level so the ends reverse position yet the level stays in the same spot on the flat surface, another "reading" is then taking, the two are compared and adjustments can then be made.Most levels are not adjustable and even fewer have spare parts available, it is possible to order a replacement vial for the Starrett precision level and if used as intended this quality of level can easily be passed from generation to generation.
The discovery of argon was not recorded to that level of precision.

Engineers use blueprints so that they can see what the height and width of a object is going to be and how to make it.
