1 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. When we convert a smaller unit to a larger unit, we divide by the conversion factor. Carpentry: Units of Measure Study Guide 3(A&B) FB/2015 Page 1

2 Example 1: A two by four measures 6 feet 8 inches. How long is it in inches? Solution: As 1 foot = 12 inches, the conversion factor is 12. Since we are converting a larger unit (feet) to a smaller unit (inches), we multiply by feet = 6 x 12 = 72 inches. Then we need to add the 8 inches to the 72 inches. 6 feet 8 inches = = 80 inches Or we can write it in a shortened way, using quotation marks: represents feet and represent inches. So 6 8 = 80 Example 2: How many pints or cups are in 1 gallon of milk? Solution: 1 gallon = 4 quarts - 1 quart = 2 pints So 1 gal. = 4 quarts x the conversion factor of 2 = 8 pints. 1 pint = 2 cups so 8 pints x the conversion factor of 2 = 16 cups. Example 3: A piece of wood measures 300 mm, how much is that in inches? Solution: 25.4 mm = 1 inch We are converting from a smaller unit (mm) to a larger unit (inches), so we divide: 300 mm 25.4 = So 300 mm is equivalent to 11.8 Carpentry: Units of Measure Study Guide 3(A&B) FB/2015 Page 2

5 UNITS OF MEASUREMENT: B. THE METRIC SYSTEM The metric system is used in most countries of the world, and the United States is now making greater use of it as well. The metric system does not use inches, feet, pounds, and so on, although units for time and electricity are the same as those you use now. An advantage of the metric system is that it is easier to convert from one unit to another. That is because the metric system is based on the number 10. The basic unit of length is the metre. It is just over a yard. In fact, 1 metre 1.1yd. (Comparative sizes are shown) 1 Metre 1 Yard The other units of length are multiples of the length of a metre: 10 times a metre, 100 times a metre, 1000 times a metre, and so on, or fractions of a metre: of a metre, of a metre, of a metre, and so on. Metric Units of Length 1 kilometre (km) = 1000 metres (m) 1 hectometre (hm) = 100 metres (m) 1 dekametre (dam) = 10 metres (m) 1 metre (m) 1 decimetre (dm) = 1 centimetre (cm) = 1 metre (m) 10 1 metre (m) 100 dam and dm are not used much. 1 millimetre (mm) = 1 metre (m) 1000 You should memorize these names and abbreviations. Think of kilo- for 1000, hecto- for 100, and so on. We will use these prefixes when considering units of area, capacity, and mass (weight). THINKING METRIC To familiarize yourself with metric units, consider the following. 1 kilometre (1000 metres) is slightly more than 21 mile (0.6 mi). 1 metre is just over a yard (1.1 yd). 1 centimetre (0.01 metre) is a little more than the width of a paper-clip (about 0.4 inch). 1 cm Carpentry: Units of Measure Study Guide 3(A&B) FB/2015 Page 5

6 1 inch is about 2.54 centimetres 1 millimetre is about the width of a dime The millimetre (mm) is used to measure small distances, especially in industry. 2 mm 3 mm The centimetre (cm) is used for body dimensions and clothing sizes, mostly in places where inches were previously used. 120 cm (47.2 in.) 3 ft 11in. 53 cm (20.9 in.) 39 cm (15.3 in.) The metre (m) is used to measure larger objects (for example, the height of a building) and for shorter distances (for example, the length of a rug) 25 m (82 ft) 3.7 m (12 ft) 2.8 m (9 ft) The kilometre (km) is used to measure longer distances, mostly in situations in which miles were previously used. Carpentry: Units of Measure Study Guide 3(A&B) FB/2015 Page 6

7 MENTAL CONVERSION AMONG METRIC UNITS When you change from one unit to another you can move only the decimal point, because the metric system is based on 10. Look at the table below: Units km hm dam m dm cm mm Example: Complete: 8.42 mm = cm Think: To go from mm to cm will mean I will have fewer cm than mm because cm are larger than mm. So I move the decimal point one place to the left mm so, 8.42 mm = cm Example: Complete: km = cm Think: To go from km to cm means that there will be many more cm than there were km because cm are smaller than km. So I move the decimal place to the right 5 places km so, km = cm Example: Complete: 1 m = cm Think: To go from m to cm m are bigger, and cm smaller so, there will be more cm than I started with. I can move the decimal place to the right 2 places. 1 m = 1.00 m 1.00 cm so, 1m = 100 cm Make metric conversions mentally as much as possible. The most commonly used units of metric measurement are: km m cm mm Carpentry: Units of Measure Study Guide 3(A&B) FB/2015 Page 7
