What is the relationship between the size of the unit and our lives?

Quantity and Unit

Is it difficult if you go to a shop to buy granulated sugar and say "Mom, buy IDR 10.000 granulated sugar?"

Well, I'm confused, how much sugar will I get for IDR 10.000  Well, that's when this unit comes. Unit is a life savior. How come? Who is the unit? Let's see the explanation bestie :)

In everyday life there are many things that we do not realize that we are studying physics or applying physics concepts. For example, when we walk, boil water, clean up tables and chairs, it's all physics. It's crazy how cool physics is.

Now, we will focus on discussing the quantities and units.

Quantity and Unit

First, let's get acquainted with QUANTITY. Quantity is something that we measure and can be expressed with numbers. So here's an example to make it clearer who the quantity is, we once measured water into a measuring cup when we were making cake batter. Now, measure the amount of water using a measuring cup and the result is for example 250 ml. That's the quantity. Eits, but not everything that can be measured can be called a quantity, you know. For example, "I love you so much". Love doesn't have a unit, and we can't express it in numbers. So it can't be called a quantity.

Maybe you can try to give another example of something that can be measured but cannot be expressed in numbers, write it in the comments.

Well, if we talk about quantities, it won't work if we don't discuss the units, because they can't be separated.

A unit is something that always follows a quantity. In more detail, we will look directly at the various quantities.

OK continue...

There are also types of quantities, namely Principal Quantities and Derived Quantities

#Principal amount

Principal quantities are quantities that have been determined beforehand and do not depend on other quantities, so this quantity is independent, independent, independent, so what are you doing.

There are 7 basic quantities, namely:

1. Mass

Mass is a quantity that expresses the quantity of an object. More details when weighing granulated sugar. For example, buy 10 kilograms of sugar. Now the kilogram (kg) is a unit of mass. An example of a mass measuring device is the scales.

2. Length

Length has units of meters (m). For example, when measuring the length of the blackboard, the length of the blackboard measured using a meter results in 2 meters.

3. Time

Time is the next basic quantity which has units of seconds (s). For example, Doni ran 100 meters in 48 seconds. The measuring instrument used is a stopwatch.

4. Strong Current

Current strength is measured using an ammeter. While the unit of current strength itself is the ampere (A).

5. Temperature

Temperature is measured using a thermometer and has units of Celsius (C).

6. Light Intensity

This light intensity has units of candela (Cd).

#Derivative Quantity

Derived quantities are quantities that are derived from the base quantity. Or simply a derived quantity is a quantity consisting of 2 or more principal quantities.

Here is an example

The unit speed is m/s, which consists of the principal quantity of length and the principal quantity of time.

For example, just one, don't take too many, the rest, my friends, write it down, try it in the comments column, ehehe

See ya :)
