A ruler or a measuring tape could be used to measure the dimensions (length, width, height) of a rock, while a scale can determine its weight. For irregularly shaped rocks, a water displacement method can be used to calculate volume, which can then be used to estimate density or mass.
Copper is widely used for; Electrical Cables, Transformers, Inductors, Water and Gas Pipework (usually pipes of 8-28mm diameter). Usually domestic hot-water cylinders, are also made from Copper. Although Cold water tanks, are frequently now plastic.
Copper wire is commonly used in electrical wiring for buildings, homes, and industrial facilities. It is also used in telecommunications and data networking applications for transmitting signals. Additionally, copper wire is used in various consumer electronics and appliances.
Sodium hydroxide is commonly used to make copper sulfate from copper oxide, which is insoluble in water. The reaction between copper oxide and sodium hydroxide forms copper sulfate and water.
A thermometer is the most common apparatus used to measure temperature. It typically contains a liquid such as mercury or alcohol that expands or contracts in response to temperature changes, allowing the user to read the temperature from a scale. More modern thermometers may use digital technology to provide temperature readings.
A sundial
Newton meter (N).
spirometer
Hook pan is laboratory apparatus used to measure or carry weights. This apparatus is also commonly used for small measurements.
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.

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.
These instruments are called salinometers (of different types).
