What is a unit of measurement?
A unit of measurement is a quantity of physical property that is standardized. It is used as a factor to express the trait of that property that exists.
An easy unit widely known by everyone helps understand the measurement relation of one object with another object. That easy unit is called a standard unit of measurement. A metric system defines units of measurement that are accepted universally as a method of measurement.
Although we use measures in everyday life, it is difficult to grasp how these measurements work. So let us help you understand different measurements.
The different types of measurements are as follows:
- Weight: Weight is a measurement of how much an object weighs, that is, how heavy it feels when you lift it.
- Length and Distance: The length of an object is means measuring how long it is, while distance is the length between 2 objects or places.
- Capacity: The capacity of an object means how much quantity it can hold.
- Time: Time is a measurement used to understand the duration from one point in our lives to another.
- Temperature – Temperature tells us how hot or cold something or the weather is.
Types of Units of measurements
- Meter (m) – Distance/Length
- Kilogram (kg) – Weight
- Second (s) – Time
- Celcius (C) – Temperature
- Litres (L) – Capacity
International System of Units
So you go to the market to get candies and chocolates. Those sweets cost you INR 500. So you give the shopkeeper an INR 2000 note because you do not have an INR 500 currency note.
What if the shopkeeper gave you 1500 USD instead? That will not be of any use to you because you would not be able to use it.
Similarly, humans came up with a system called the International System of units. This system makes it easy for people everywhere to talk about things in a way clear manner.
The International System of Units has seven base units for each type of physical quantity. A physical quantity is an object’s measurable property. Examples of physical quantities are the length of an object and capacity.
Base quantities and derived quantities are the two types of physical quantities.

Derives quantities are those units that get derived from other base quantities.

Some important FAQs
What are the units of standard measurement in the Metric System?
The most common and widely used system of units is the Metric System. Here are some of the standard and non standard units of measurement of the Metric system:
- Millilitres (ml)
- Litres (l) – This is the standard unit of capacity.
- Grams (gr)
- Kilograms (kg) – This is the standard unit of weight in India.
- Tonnes (t)
- Newton (N) – This is the standard unit of weight per the International System of of Units.
- Millimetres (mm)
- Centimetres (cm)
- Metres (m) – This is the standard unit of length.
- Kilometres (km)
- Seconds – This is the standard unit of time.
- Degrees Celsius (C) – This is the commonly used unit for temperature in India.
- Kelvin (K) – This is the standard unit of temperature per the International System of of Units
What is a unit and standard unit?
A unit is any standard used to compare measurements. Unit conversions allow conversion of property measurements from one unit to another, such as centimetres to inches.
A standard unit of measurement is a set type of value that does not vary from person to person or location to location.
Standard units of measurement help standardize measurements.
The standard unit of length is the metre, represented by the symbol (m).
What is the standard unit of measuring land?
The standard unit of measuring land is Hectare, where 1 Hectare = 2.4 Acres. Acres is a commonly used unit in India, so you might get confused if someone says, Acre. But note that in the international system of units, Hectare is the standard unit of measuring land.
What are the examples of standard units?
Examples of standard units:
- Kilogram (kg): Mass is measured in Kilogram
- Meters (m): Distance is measured in Meters
- Seconds (s): Time is measured in seconds
Why do we need standard unit of measurement?
To make the judgment more trustworthy and precise, we need a standard unit of measurement. Everyone’s measurement should be the same for proper dealing. As a result, measurement should be consistent. We require a standardized set of measuring units, known as standard units, to ensure uniformity. Nowadays, SI units are nearly generally recognized in research and technology.
Important things to note
- If a quantity has dimensions, it should have an association with units.
- Physical quantity dimensions refer to the nature of the amount in some measurable terms. L, M & T represent physical dimensions, which stand for length, mass, and time, respectively.
- The physical quantity gets measured with a fundamental unit determined by and widely recognized across the world. The measurement outcome includes a number accompanied by a measurement unit.
- Other additional units are physical quantities having no dimensions. These units get used in conjunction with basic units.
