International System of Units (SI)
Definition - What does International System of Units (SI) mean?
The International System of Units (or SI, from the French "Le Système international d'unités") is a globally recognized measurement system applicable in science, commerce, industry, medicine and everyday use.
It is composed of different units of measurement in a coherent system. The base units can be used to measure elements such as:
The International System of Units is also known as the metric system.
Petropedia explains International System of Units (SI)
The International System of Units is a scientific way to express quantities, magnitudes and other properties of various elements and materials. This system of measurement is composed of seven base units, with several subunits. It was previously known as MKS (Meter Kilogram Second) system.
Nearly every country in the world uses the SI system. This universal standardization greatly simplifies matters dealing with science, business and industry because no additional calculation or translation is needed.
In proper and effective functioning of equipment, machines, infrastructure setup of oil and gas, numbers and measurement play important and crucial role. Therefore, the SI system is a very effective and efficient tool which has standardized the measurement parameters globally for measurement elements such as pressure, temperature, weight, volume, energy, time, etc. For instance, learning how to properly measure temperature by referring to the SI system can be helpful in maintaining the correct operating temperatures of the equipment or determining the proper level of temperature needed to hinder the damaging effects. This idea can also be applied in other areas of measurement.
