What is Metric Organisation?
The metric system is a organization of measuring things. It is used worldwide in calculations and research. Here are some examples of how we measure things using the metric organization:
- Meter is the unit of measuring distances and lengths. We use this unit of measurement in our daily life, for case, the distance betwixt schoolhouse and home, length of material, etc.
- Yous may have noticed that there is a weight mentioned in the bag of your favourite snack. For example, 250 grams of potato chips. Here, gram is the unit of weight.
- Similarly, on the bottle of your favourite drink, there’s volume mentioned (for example, 250 milliliters of cola). Here, milliliter is the unit of volume.
Metric Units
The units for length, weight (mass) and capacity(book) in the metric system are:
Length:
Millimeter (mm), Decimeter (dm), Centimeter (cm), Meter (m), and Kilometer (km) are used to measure out how long or broad or tall an object is.
Examples include measuring the thickness or length of a debit carte du jour, length of cloth, or distance between two cities.
Weight:
Gram (g) and Kilogram(kg) are used to measure how heavy an object is, using instruments.
Examples include measuring the weight of fruits or our own body weight.
Capacity:
Milliliter (ml) and Liter (fifty) are used to measure how much quantity of liquid an object can concord.
Examples include measuring the amount of juice in a juice tin, or amount of water in a water tank.
Metric Conversions
The metric system is a system of measurement that uses the meter, liter, and gram every bit base units of length (distance), capacity (volume), and weight (mass) respectively.
To measure smaller or larger quantities, we use units derived from the metric units.
- The given figure shows the arrangement of the metric units, which are smaller or bigger than the base unit of measurement.
- The units to the right of the base unit are smaller than the base of operations unit. As nosotros motility to the right, each unit of measurement is ten times smaller or one-tenth of the unit to its left. So, a ‘deci’ ways one-tenth of the base of operations unit, ‘centi’ is one-tenth of ‘deci’ or 1-hundredth of the base unit and ‘milli’ is 1-10th of ‘centi’ or one-hundredth of ‘deci’ or one-thousandth of the base unit.
- The units to the left of the base unit of measurement are bigger than the base unit of measurement. Equally we motion to the left, each unit is 10 times greater than the unit to its right. So, a ‘deca’ means 10 times of the base of operations unit, ‘hecto’ is ten times of ‘deca’ or hundred times of the base unit of measurement and ‘kilo’ is ten times of ‘hecto’ or yard times of the base unit of measurement.
Here’southward how we can multiply or carve up for making metric conversions. To catechumen a bigger unit of measurement to a smaller unit of measurement, we move left to right, we multiply by 10. Moving correct to left, from smaller units to bigger, nosotros divide by 10.
The Metric Arrangement in Our Daily Life
Nosotros use the metric system in our daily life in many ways. Let us expect at some everyday examples of the metric organisation.
- Water in a tank or a liquid in a container is measured in liters. It is the metric unit of measurement of book.
- When we travel in a vehicle, we measure the distance travelled in meters or kilometers.
- When we buy groceries, they are measured in weight units such equally grams and kilograms.
The US Standard Units or the Customary/Imperial Organization units.
This system measures:
- Length or distance in inches, feet, yards, and miles.
- Capacity or volume in fluid ounces, cups, pints, quarts or gallons.
- Weight or mass in ounces, pounds and tons.
Solved Examples
Question one: What exercise the following values and units betoken: 20 meters, 150 kilometers, 50 meters?
Answer: Meters and kilometers are units used to signal length or distance.
Question ii: What are different
measuring units
for meridian?
Reply: Summit can exist measured with the units of length measurement. Therefore, in a metric arrangement, height can exist measured in meters, and centimeters.
Question 3: In what units can the following be measured:
- A bag total of apples
- A saucepan of h2o
Answer: A bag total of apples can be measured with weight units such as kilograms or grams. A saucepan total of water tin can exist measured with units of volume, such equally a liter.

Meter
Liter
Grams
Kilometer
Correct reply is: Grams
Grams are the unit of weight.
Distance
Weight
Volume
Length
Correct answer is: Weight
Kilogram is a unit of weight.
Liter
Kilogram
Grams
Meter
Correct answer is: Liter
Liter is the unit of measurement for liquid matter.
feet
Liter
Gram
Meter
Right answer is: feet
Feet is not a metric unit. It is an imperial system of units.
Conclusion
Every twenty-four hours, nosotros measure out weights, lengths, distances, etc. The system that is followed for such measurements is chosen the metric system. Meter, liter, and gram are the basis of measurement for length, volume, and weight respectively.

Ofttimes Asked Questions
What are metric prefixes?
Metric system of measurement have prefixes such as “deka, hecto, and kilo” pregnant 10, 100, and 1,000 and “ deci, centi, and milli” meaning $\bigg(\frac{i}{10}\bigg)^{th}$ , $\bigg(\frac{1}{100}\bigg)^{th}$ , and $\bigg(\frac{1}{1000}\bigg)^{th}$ respectively with the name of the unit of measurement
How did people measure things before the metric system?
Earlier the metric organisation, people effectually the world used their own standards for the measurement of various objects.
How is the metric organization different from the imperial system?
Metric and imperial systems are systems for measuring dissimilar values. Most of the countries use metric systems as the standard for measurement. Now, merely three countries use imperial systems. These are the The states, Vietnam, and Republic of liberia.
Is meter a unit of distance?
Yep, the meter is a unit of altitude.
