A graduated cylinder, also known as measuring cylinder or mixing cylinder is a common piece of laboratory equipment used to measure the volume of a liquid. It has a narrow cylindrical shape. Each marked line on the graduated cylinder represents the amount of liquid that has been measured.

This range or span is a graduated scale and the minimum value of displayed graduation is the ‘least count’ or ‘resolution’ of the instrument. The least count of a scale can only be 1, 2, 5, 10 and their multiples. The least-count/resolution relates more to readability of a weighing instrument, rather than accuracy.

Metric System Generally, a metric graduation is included on the opposite side of the ruler from the imperial graduation, allowing for easy measurement in both units. A typical steel ruler features a scale of 30 centimeters, each divided into 10 increments of 1 millimeter each.

Nanoscale materials have far larger surface areas than similar masses of larger-scale materials. As surface area per mass of a material increases, a greater amount of the material can come into contact with surrounding materials, thus affecting reactivity.

: a microscopically small robot : a robot built on the scale of nanometers Many newspaper articles about nanotechnology seem obsessed with the idea of nanobots, itty bitty robots that dash about doing useful tasks and maybe (just maybe) getting out of control and destroying the world …—

What are nanobots used for? Currently, nanobots are mostly used in the field of medicine to deliver drugs, operate on internal injuries, and even combat cancer. Nanobots are orders of magnitude smaller than a human cell, generally at the scale of a micrometer (which corresponds to one-millionth of one meter.)
