Measurement•is the process or the result of

determining the magnitude of a quantity, such as length or mass, relative to a unit of measurement, such as a meter or a kilogram.

Types of Measurement System & Units

• Imperial System

• Metric System

• International System Unit

• Distance

Metric System• is an international decimalized system of

measurement.

• first adopted by France in 1791, that is the common system of measuring units used by most of the world. It exists in several variations, with different choices of fundamental units, though the choice of base units does not affect its day-to-day use

• One goal of the metric system is to have a single unit for every physical quantity.

Metric System Units and Symbols

Quantity Measured

- length, width,distance, thickness, girth,

Millimeter (mm) 10mm=1cm centimeter (cm) 100 cm=1m

meter (m)   

kilometer (km) 1km = 1000m

Metric System Units and Symbols

Quantity Measured

- Mass (“weight”)*

Milligram (mg) 1000mg =1g gram (g) 1000g = 1kg

kilogram (kg)   

metric ton (t) 1t = 1000kg

Metric System Units and Symbols

Quantity Measured

- Time

second (s) 60s =1m minute (min) 60min =1h

hour (h)   

Metric System Units and Symbols

Quantity Measured

- Volume

milliliter (mL) 1000mL =1L cubic centimer (cm³) 1cm³ =1mL

liter (L)    1000L = 1m³

cubic meter (m³)

Metric System Units and Symbols

Quantity Measured

- Area

square meter (m²)   

hectare (ha) 1 ha=10 000 m²square kilometer (km²) 1 km²=100 ha

Application

• The application in learning the metric system is converting the metric units

eg. Convert the following measurements

a.  8 cm to mm

b.  6 m to cmc.  7 km to m

PROBLEM AND SOLVING

Toni was told that he had jumped 8.21 m by an official and 0.0082 km by a friend.  Which was the greater measurement?

Solution

It makes my life EASY!!

• In buying foods it becomes easy if you know how to use metric system

It makes my life EASY!!

• In our work place we use metric system in measuring our daily activities through time.

It makes my life EASY!!

• In doing buildings and landscape structures. We use the metric system

ConclusionTherefore, the importance of metric

system is to provide human being the easiest way of living. Imagine if there is no metric system. It might be tough and hard for us in dealing problems or numbers the would involve measurement. Metric system is one of the greatest discoveries of the modern mathematicians and everybody should learn about it and see its importance.

“The essence of mathematics is not to make simple things complicated, but to make complicated

things simple.”
