What is Measurement? Measurement is a way to find out a product’s length, weight, area etc. We all use measurement, but sometimes we don’t even notice We use measurement in our daily life, like:
How We UseMeasurement in Our Life By looking at our watches, we measure time By giving people directions, we measure distance By using our ruler, we measure length By stepping on a weigh, we measure weight We use measurement all the time!
Different Systems of Measurement๏ There are different measurement systems all over the world: There is the Customary System, which was the system they used before but we still have now, Later on the UK invented the Metric System๏ Some other systems include: Natural units and Non-Standard Units๏ Let’s focus on the Customary System and the Metric System......
Customary System✤ Some units of the Customary System include: miles, pounds, gallons, teaspoons, tablespoons, cups. Seem familiar?✤ The Customary System is based on the Imperial System✤ We still use some of the Customary Units, but not that often now that we have the Metric System.✤ I’ll explain on the next page......
Metric SystemSome Metric Units are: Kilometer, Centimeter, Decimeter,Millimeter, Picometer, Nanometer......But the 6 main ones are: Kilo-, Hecto-, Deka-, Deci-,Unit(1), Centi- and Milli-.One way to memorise them is: King Henry Doesn’tUsually Drink Chocolate Milk.Fact: the units of the metric system are all multiples of10Kilo means 1,000, Hecto means 100, Deka means 10,Unit means 1, Deci means 0.1, Centi means 0.01, andMilli means 0.001
Tools of MeasurementThere are different tools for The Clock-tells you the time/measurement and geometry, measures timeand some of them include: The Scale/Weigh-used toThe Compass-lets you draw measure your weight andarcs and circles massThe Protractor-helps you The Thermometer-tells you themeasure angles temperatureThe Sextant-used by sailors to The Measuring Cup-measuresfind their position on the sea capacityThe Ruler-helps you measure These are just some of thethe length of things and draw many measuring tools thatstraight lines we have in our world, there are a lot more
Converting Between Units Lets start with the metric 12 inches=1 foot system: 3 feet=1 yard 10 milli- =1 centi- 5280 feet=1 mile 10 centi- =1 deci 16 fluid ounce=1 pint 10 deci- =1 unit 2 pints=1 quart 10 units=1 deka 4 quarts=1 gallon 10 deka=1 hecto 16 ounces=1 pound 10 hecto=1 kilo 1 ton=2000 pounds Now, for the customary system:
Connections BetweenMaterials and Measurement (Measuring materials) What materials you can measure Wood, Metal, Glass, and others. Even some measurement tools are made from materials!
