Someone told me a micrometer?
The numbers like .75 .50 indicate the oversize of the piston ring that will be used for repair. For instance if the engine has a diameter of 70 mm and you need to open the cylinder bore for repair in .50 mm, you need to use one piston ring with diameter 70.50 mm.
The term rotary piston engine can have several meanings:Rotary engine, the piston engine that rotates in operation, as used on World War I fighter aircraftPistonless rotary engine, the engines which use rotors or rotary pistons instead of conventional reciprocating pistons
You can measure the diameter, then divide that by 2.
Tape measure
A vernier caliper should be used to measure the diameter of a steel ball.
You mean a piston ring. It seals the gap between the piston and the chamber in your engine
It is in a cargo ship. The piston weighs 10 tons by itself.
Yes, a calibrated ocular micrometer can be used to measure the diameter or length of a field or object. Essentially, that is all that it is used for.

The clearance between the piston and cylinder is maintained by the piston rings, the ring centers the piston within the cylinder bore and is the device that seals the cylinder bore and creates and maintains the pressure created by the piston movement in the bore. When assembling an engine you will need to check and set end gap of the rings, this is done by centering the new ring in the bore and measuring the gap between the ring ends, you can measure this distance with feeler gauges and adjust by filing the ends of the rings to increase to the recommended tolerance, this tolerance is measured in .000 of an inch and different engines require different end gaps. This end gap is determined by the diameter of the bore with the greater the bore diameter than the greater the end gap,.
Vernier calipers can be used to accurately measure a hard rod's diameter within seconds. And it's very easy to use.
