How about a micrometer
A ruler that can measure very small units.
For surveying, there are some use of tools. Look at them, The Dividing Engine, Chains, Calculating device (non electric), leveling machine , strange and some other. These tools are very unique to use.
When they need an approximate measurement. The scales used to weigh a truckload of gravel are not as accurate as laboratory scales that can measure the weight of a pencil mark on a bit of paper- but extreme accuracy is not needed for the gravel truck.
You measure it very, very carefully!
a "n-m per second" is a measure of speed, not of distance. At that speed something can be very, very near if measured for a very short time or it could be millions of light years away if measured for a sufficiently long time. The question, therefore, makes no sense.
There is no instrument in world which measure how small an object is but instruments measure how large an object is .
a telescope ! or binoculars
tuba
This depends on the length of the object.You can use mm for very short objects, cm for short objects, m for long objects; and working with a microscope we use μm.
A parallax is hard to measure if it is very small - and this happens when the corresponding object is very far away.
multimetre connected with a rheostat
it is used to measure very high voltages which can not be measured with volt meter.
This object is very heavy weight.
A ruler that can measure very small units.
Use a graduated cylinder to precisely measure volume
A theodolite is a precision measuring instrument used to measure angles in the horizontal or vertical plane. The instrument is mounted on a tripod and should be very precisely placed in order to make correct measurements.
