Measurement Meaning

What is Measurement:

Measurement is the action of measuring, that is, determining through instruments or through a previous relationship or formula a result within the chosen parameters.

Measurement derives from the verb to measure, which in turn comes from the Latin word metriri which means “to compare a result or quantity with a previous unit of measurement”.

The measurement serves to determine magnitudes of an object in relation to another object that serves as a pattern, which is previously defined by consensus. Today, these comparison models that we use every day, such as the kilogram, the temperature and the centimeters, are unified in what is known as the International System of Measurements (SI).

In this system, the units of measurement that we use to relate individually, socially and economically were established. In this sense, measurement is important because it facilitates the exchange of times, spaces, objects and theories.

Measurement type

The types of measurement can be classified according to the way of obtaining the measurements, direct measurements and indirect measurements; the area in which the measurement will be used, such as physical, chemical and biological measurement; and according to the measurement units such as temperature measurement in celsius (C°) or fahrenheit (F°).

direct measurement

Direct measurement refers to obtaining the result immediately using measuring instruments, such as using measuring tapes to measure height, using scales to weigh fruits, and timing a friend with a stopwatch.

Direct measurements are used in everyday life but also in laboratories. In chemistry, for example, the weight of each substance to create solutions is a direct measurement with a balance calibrated for those purposes.

indirect measurement

Indirect measurement is characteristic of measurements in which a sequence of formulas and data from previous investigations are required. In this sense, indirect measurements are characterized because they obey scientific methods due to their complexity. Objects of study that require different levels of measurement are measured, such as the measurement of social inequality and the measurement of gravitational waves.

Measurement systems

The measurement systems are patterns of scales defined under a consensus. The International System of Measurements (SI) is the most widely used system to determine physical quantities. The 7 SI base units are: meter (distance), kilogram (mass), second (time), ampere (electrical current), kelvin (temperature), candela (luminous intensity), and mole (weight of chemicals).

The 7 basic units are defined by scientific methods, with the exception of the kilogram, whose standard has been preserved since 1960 in the International Bureau of Weights and Measures.

Measurement tools

To make a measurement we have measuring instruments such as the ruler, the scale and the thermometer, which have certain units of measurement. Anything we use to help us measure is called an instrument, tool, or measuring apparatus.

Measurements for scientific investigations, the rigor of the measurements is greater and, therefore, more precise and calibrated measuring instruments are necessary, such as analytical balances.
