What efforts are made to bring uniformity in measurement​

The use of S I Unit brings uniformity in measurements.

Explanation:

The S I unit is the international system of units which are used to express the magnitudes or quantities of important natural phenomena. It is used universally as a standard for measurements thereby creating an avenue for uniformity in measurements. The base units that makes up the SI unit are:

--> Length: this is measured in meters (m)

--> Time: this is measured in seconds (s)

--> Mass: this is measured in kilogram (kg)

--> Temperature: this is measured in Kelvin (k)

--> Electric current: this is measured in ampere (A).

--> Amount of substance: this is measured in mole

--> Luminous intensity: this is measured in candela (cd)

These units are used as the standard to make our judgement of measurement more reliable and accurate. And since there is only one basic unit for each quantity (example length which is measured in meters) there is no need for further conversions.

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
