  • Linear Measures: the Metric System
    Units of Measurement: A. The Imperial System Canada uses the metric system – most of the time! However, there are still places and occasions where the imperial system of measurement is used. People often talk about their height in feet and inches or their weight in pounds. Many recipes measure in cups and teaspoons. Another example is the term ‘two by four’ when talking about lumber. That term means that a plank is roughly two inches thick and four inches wide. Another place where the imperial system of measurement is often seen is in the grocery store, especially in the meat/fish and fresh produce sections. Prices and weights are often given in both metric and imperial units of measurement. For example, you may see a sign advertising “Potatoes – 89¢ a pound (lb.) or $1.96 per kilogram (kg)”. The USA uses only a system of measurement related to the imperial one, so items imported from there often do not have a metric equivalent given. Cookbooks frequently use one or the other system of measurement. For all these reasons, it is important to understand both systems and be able to convert one into the other. The most common imperial units of measurement are: Quantity Unit Symbol length foot ft. weight pound lb. volume gallon gal. Here are the most common conversions of imperial units of measurement: Length Weight Volume 1 foot (ft. ) = 12 inches (in.) 1 pound (lb.) = 16 ounces (oz.) 1 pint (pt.) = 2 cups 1 yard (yd.) = 3 feet 1 ton = 2000 pounds (lbs.) 1 quart (qt.) = 2 pints 1 mile (mi.) = 5280 feet or 1760 yards 1 gallon (gal.) = 4 quarts When we convert units in the imperial system, we use a familiar rule: When we convert a larger unit to a smaller unit, we multiply by the conversion factor.

  • Units and Conversions the Metric System Originates Back to the 1700S in France
    Numeracy Introduction to Units and Conversions The metric system originates back to the 1700s in France. It is known as a decimal system because conversions between units are based on powers of ten. This is quite different to the Imperial system of units where every conversion has a unique value. A physical quantity is an attribute or property of a substance that can be expressed in a mathematical equation. A quantity, for example the amount of mass of a substance, is made up of a value and a unit. If a person has a mass of 72kg: the quantity being measured is Mass, the value of the measurement is 72 and the unit of measure is kilograms (kg). Another quantity is length (distance), for example the length of a piece of timber is 3.15m: the quantity being measured is length, the value of the measurement is 3.15 and the unit of measure is metres (m). A unit of measurement refers to a particular physical quantity. A metre describes length, a kilogram describes mass, a second describes time etc. A unit is defined and adopted by convention, in other words, everyone agrees that the unit will be a particular quantity. Historically, the metre was defined by the French Academy of Sciences as the length between two marks on a platinum-iridium bar at 0°C, which was designed to represent one ten-millionth of the distance from the Equator to the North Pole through Paris. In 1983, the metre was redefined as the distance travelled by light 1 in free space in of a second.

    7 Measurements 1 Measurement Different units of measurement have been used in the past, some of them are still in use in UK and USA, but in most places is used the Metric System of Measurements. The metric units are: Length metre (In U.S.A. “meter”) Area square metre Volume cubic metre Capacity litre Mass or weight gram It is very useful to be able to estimate lengths, masses, etc. because it may not always be easy to measure them. Some useful hints for estimating are listed below: The height of a standard door is about 2 m. The length of an adult pace is about 1 m. The length of a size 8 (41 in Spain) shoe is about 30 cm. Most adults are between 1.5 m and 1.8 m in height. It takes about 15 minutes to walk one kilometre. The mass of a standard bag of sugar is 1 kg. The mass of a family car is about 1 tonne. 2 hectares = 20 000 m2 (about 3 football pitches). A teaspoon holds about 5 ml of liquid. The volume of a normal can of drink is about 330 cm3. In England some imperial units are in common use today. People may for example give their height in feet and inches; give a distance in miles, their weight in stones or a capacity in gallons. We will see the relationships between the units of the Imperial and the Metric systems of measurement. 7-1 I.E.S. “Andrés de Vandelvira” - Sección Europea Mathematics 2 Metric Prefix Table The metric (decimal) system uses a number of standard prefixes for units of length, mass, etc.

  • Unit 7. Metric System Measurement
    st English Maths 1 ESO. Bilingual section at Modesto Navarro UNIT 7. METRIC SYSTEM MEASUREMENT. 1. INTRODUCTION TO THE METRIC SYSTEM. Wow, I have just flown in from planet Micron. It was a long flight, but I wanted to spend some time with you! My name is Maggie in your language (but you couldn't pronounce my real name!) When I first arrived I couldn't understand how you measure things, but my teacher taught me all about measurement, and I am going to tell you everything he taught me. The first thing Tom told me was that you can measure things using two different systems: Metric and US Standard. Today is my day and your day to learn Metric. My teacher says that if I understand 10, 100, and 1000 then it will be very easy to learn the metric system. I wish I had ten fingers! 2. LENGTH. Measuring how long a thing is, how tall it is, or how far it is, are all examples of length measurements. The metre is the most important unit of length. We write it m. UNIT 7. METRIC SYSTEM MEASUREMENT 1 st English Maths 1 ESO. Bilingual section at Modesto Navarro Tom says I must know above all: - Millimetres. - Centimetres - Metres. - Kilometres. Millimetres: The smallest units of length are called millimetres. A millimetre is about the thickness of a plastic credit card. Or about the thickness of 10 sheets of paper on top of each other. This is a very small measurement! Centimetres: When you have something that is 10 millimetres, it is 1 centimetre.

  • 1.1 SI Measurement
    Foundations & Pre-Calculus 10 1.1 SI Measurement In Canada, we use a system of measurement called SI (Système International d’Unités). This system of measurement is based on the metre. The other units of this system are based on the metre multiplied by a factor of 10. Here is a table of the main units used in the SI system of measurement. Unit Abbreviation Multiplying Factor kilometre km 1000 (103) hectometre hm 100 (102) decametre dam 10 (101) metre m 1 (100) decimetre dm 0.1 (10-1) centimetre cm 0,01 (10-2) millimetre mm 0.001 (10-3) When taking measurements of objects, we can either make an estimate or make an exact measurement. When making estimations, we can use an object as a measurement unit. This object is called a ________________. Some examples of __________________ and their approximate sizes are: Estimating using a Referent 1) For each object, use an appropriate referent to estimate its size. a) The thickness of your textbook Referent: Estimate: b) The length of your pencil Referent: Estimate: c) The height of your classroom Referent: Estimate: : 8 When making exact measurements, there are several instruments that can be used. Some examples would be: Reading a Caliper: To read a Vernier caliper with a sliding scale, follow these steps while using the diagram as an example. 1) Read the value of the fixed scale where it lines up with the zero on the sliding scale. This will give the whole number and the tenth value of the measurement. Ex. From step 1, we have the item measuring ______________________.

  • Centimetres Or Millimetres
    centimetres or millimetres Which will you choose? Pat Naughtin In recent times, as they upgrade to the metric system, the people of each nation re-open a discussion about the most suitable small metric units for everyday use. The discussion always seems to focus on the questions: Which is best: centimetres or millimetres? and Which will you choose: centimetres or millimetres? Only occasionally does this discussion expand to include all of the small metric prefixes — centi, deci, hecto and deca, — thereby extending the discussion to centigrams, centilitres, centiseconds and all of their deca, deci, and hecto equivalents. This debate, which Australia had when it upgraded to the metric system, is currently emerging in the UK and the USA as those nations make their inevitable progress toward complete metrication. And generally the same arguments – those for and those against centimetres or millimetres – are used repeatedly in each nation. Over several years, I have collected many examples of the arguments both for and against centimetres, and for and against millimetres. There are lots of them, so I have decided to break this article into three parts. Following this introductory page, there is a summary of the main arguments for the use of centimetres or millimetres. After this, I share the main lines of argument that I have collected; this is the long part (46 pages). Finally, there is a 3 page conclusion. If you are pressed for time, I suggest that you read the first 4 pages and the last 4 pages and only skim read the bits in the middle that interest you.
