Question

metric unit system for class 5​

Answer 1

Question:

Metric unit system (class 5)

Step-by-step explanation:

The metric system is defined as the system of measurements to calculate the mass, distance, and volume of any object. We generally use the metric system to measure smaller or larger quantities.

Here is solved example:-

Example 1:

Convert 356 centimetres to meters.

Solution:

We know that, 1 cm = 0.01 m

Thus, 356 cm = 356 x 0.01

356 cm = 3.56 m.

Therefore, 356 cm is equivalent to 3.56 meters.

Example 2:

Convert 4000 grams to kilograms.

Solution:

We know that, 1 gram = 0.001 kilogram

Thus, 4000 g = 4000 x 0.001

4000 g = 4 kilogram

Therefore, 4000 grams is equivalent to 4 kilogram

Example 3:

Convert 50 kilolitres to liters.

Solution:

We know that 1 kilolitre = 1000 liters

Thus, 50 kilolitres = 50 x 1000 litres

50 kilolitres = 50000 litres

Therefore, 50 kilolitres are equivalent to 50000 liters

Some Frequently Asked Questions (FAQs) on Metric Systems

What is meant by the metric system?

Ans:- The metric system is defined as the system of measurements to calculate the mass, distance, and volume of any object. We generally use the metric system to measure smaller or larger quantities.

What are the base units for length, weight, and volume in a metric system?

Ans:- In the metric system, the base units for length, weight, and volume are meters, grams, and liters respectively.

Mention the US standard units for length, weight, and volume.

Ans:- In US customary systems, the units used are:

Distance or length in miles, yards, feet, inches

Mass or weight in pounds, tons, ounces

Capacity or volume in cups, gallons or quarts, pints, fluid ounces.

What is meant by metric number prefixes?

Ans:- The metric number prefix is defined as a unit prefix, which precedes a base unit to indicate the multiple or the submultiple of a unit. Some of the metric prefixes are:

Kilo (1000 or 103)

Hecto (100 or 102)

Deca (10 or 101)

Base unit (1)

Deci (1/10 or 10-1)

Centi (1/100 or 10-2)

Milli (1/1000 or 10-3)

Convert 80 grams to milligrams.

Ans:- We know that 1 gram = 1000 milligrams

Therefore, 80 grams = 80 x 1000 milligrams

80 grams = 80000 milligrams

Thus, 800 grams is equivalent to 80000 milligrams.
