Summary of ¿Qué es el Sistema Internacional de Unidades?

00:00:00 - 00:05:00

The video explains the rules for writing symbols for the SI, or international system of units. This system is used throughout the world and is based on the metric system. The video explains some of the units in the system and how to write their symbols correctly.

• 00:00:00 The system of international units is a system of measurement that uses the same units throughout the world. It is based on the metric system, which was developed in the 18th century. The system of international units consists of two types of units: base units and derived units. Base units are the units from which all other units are derived. Derived units represent a magnitude in magnitude of time or distance. Some of the units in the system of international units include the meter (meter), the second (second), the kilogram (kilogram), the Celsius (Celsius), the Kelvin (Kelvin), the mole (mole), the candela (candela), the degree Celsius (degree Celsius), the degree Fahrenheit (degree Fahrenheit), the watt (watt), and the second (second).
• 00:05:00 The international system of units (SI) is a system of units that does not belong to the International System of Units (SI). The SI consists of several rules for writing symbols that belong to this system. In this video, only some of the rules for composing the SI will be mentioned. The first rule is that symbols that belong to the SI should be used only if they have been approved by the conference of weights and measures. The second rule is that the characters only should be written in Roman characters. The symbol for units always starts with a small letter, except for those that derive from a name, which is explicitly prohibited from being abbreviated. The units symbol should not be replaced with a capital letter when it is written with letters, because this could affect the meaning. The units should not be represented by their symbols when they are written with letters, but their numeric value is expressed by the name of the unit intercalated between the name of the unit and the word "x." When the product of symbols is written, the symbols are simply named. In the next video, topics related to the SI will be covered, such as metrology and numerical patters.
