It is measured in cubic units like cm 3, m 3, etc. Volume: Volume is the space enclosed or occupied by any three-dimensional object or solid shape. Now that you know what an Area is, let's learn how to find the Area of a Triangle, Area of a Quadrilateral, Area of a Circle. The area is measured in square units like sq. Here we shall look at some of the other important physical quantities and their units.Īrea: The area is the space occupied by a two-dimensional shape or figure. Such quantities of the basic system are sometimes not sufficient to overcome the challenges of studying and measuring other higher quantities existing in physics. Quantities like, force, power, area, magnetic intensity, have their own individual units, which have been derived from the basic 7 quantities of the metric system of measurement. Though we are aware of the basic defined metric systems for length, mass, volume, but there are numerous other quantities in the physical world, for which we need to define the base unit. A stopwatch can be used to measure the time in seconds. We use a clock or watch to tell the current time. Some of the conversion units of time are, 1 minute = 60 seconds, 1 hour = 60 minutes, 1 day = 24 hours, 1 week = 7 days, 1 year = 12 months, or 1 year = 365 days. It also helps us to set the start time or the end time of events. It is used to quantify the duration of the events. Time is the ongoing sequence of events taking place. A doctor also used a weighing scale to find the weight of a person. A weighing scale is used in supermarkets to weigh groceries. We use a weighing scale to measure how heavy things are. In general, for our convenience, we use gram, kilogram, and milligram. We can multiply and divide the base units to measure smaller and bigger units. It tells us how heavy or how light an object is. Kilogram: Mass is measured in kilograms and the unit is denoted by (kg). For example, a pencil measured on a ruler would be 10 cm long. We can use a simple ruler to measure length. The base unit is "m" and we add "Deca," "Hecto," and "Kilo" to measure large units by successively multiplying by 10 and "deci," "centi," and "millie" successively dividing by 10, to measure smaller length. The Metric system has 3 main units namely, meter to measure the length, kilogram to measure the mass, and seconds to measure time. customary units are used across the states for measurements. US Standard Units: United States, Liberia, and Myanmar have not adopted the metric system as their official system of weights and measures. Metrics systems evolved and over time are universally accepted as the International System of Units called the SI System. are defined by seven physical constants with numerical values in terms of the units. Metric System: The units of the metric system, originally taken from observable features of nature (basically what we normally measure like the time, length, mass, etc. Let us now look at the below described, different systems of measurement. Often the required unit is either larger or much small than the defined units. The base units used in the metric system are used to derive higher and lower units of measurement. The metric system is based on the international decimal system. It was introduced in France in the 1790s and is now being used officially by many countries around the world. Introduction to Metric System of MeasurementĬonversions from One System of Measurement to AnotherĪ metric system is a system of measurement based on the standard units as a meter for length, kilogram for mass, and liter for volume. Let us learn about systems of measurement on this page. The system of measurement is based on two important foundation pillars of defining the basic unit of measurement, and the measure of conversion from the basic unit to other related units.įurther, the other related units of measurement can be in the same system of measurement or a different system of measurement. System of measurement is very important and define and express the different quantities of length, area, volume, weight, in our day-to-day communications. Even our productivity is measured in terms of productivity indexes on how productively we work. The whole world revolves around measuring things! Everything is measured: the milk you buy, the gas you fill for the vehicle, the steps you walk. It is more like a collection of units of measurement and rules relating them to each other. System of measurement refers to the process of associating numbers with physical quantities and phenomena.
