Scales with weights, Iran, 1801-1900
This elaborately decorated box contains three separate sets of scales, with a stand. It also contains weights and tweezers of varying sizes which slot into custom-made compartments. These may have been used within the medicine and jewellery trades. Both trades required the precise measurements of goods. The scales suspend two disk-shaped pans off either end of a horizontal pole. The weights in either pan must be equal for the pole to remain horizontal.

Measurement is the process of estimating the magnitude of some attribute of an object, such as its length or weight, relative to some standard (unit of measurement), such as a meter or a kilogram. The act of measuring usually involves using a measuring instrument, such as a ruler, weighing scale, thermometer or speedometer which is calibrated to compare the measured attribute to a measurement unit. Metrology is the scientific study of measurement.
