When you resist any temptation to convert a metric unit to a non-metric one, then the familiarity of using metric will soon get you to understand metric. When you see road signs like the one pictured above showing a distance in metres, this can help you get used to how long the distance is. In this case, stand at the sign, look towards the Post Office, and see how far that distance is visually, and remember that the distance is metres.
The metric system is the same the world over. A population that is highly skilled in maths and science is essential for national economic and social progress. By using only the metric system, education and training in these key subjects is much more efficient. Learn how to approximate the area more accurately by using smaller and smaller units.
Relate this counting approach to the standard area formulas for triangles, trapezoids, and parallelograms. Investigate the circumference and area of a circle. Explore several methods for finding the volume of objects, using both standard cubic units and non-standard measures.
Explore how volume formulas for solid objects such as spheres, cylinders, and cones are derived and related. Examine the relationships between area and perimeter when one measure is fixed. Determine which shapes maximize area while minimizing perimeter, and vice versa. Explore the proportional relationship between surface area and volume. Construct open-box containers, and use graphs to approximate the dimensions of the resulting rectangular prism that holds the maximum volume.

The Metric System Mathematics K-2 , , Notes Note 1 Most Americans are not very comfortable using the metric system.
Session 2 Fundamentals of Measurement Investigate the difference between a count and a measure, and examine essential ideas such as unit iteration, partitioning, and the compensatory principle. Also, notice that two new prefixes have been added here: mega- which is very big and micro- which is very small.
When applying the factor label method in the metric system, be sure to check that you are not skipping over any intermediate units of measurement! Using the factor label method, write 7, cm as a fraction and use unit fractions to convert it to m. If you have a prescription for 5, mg of medicine, and upon getting it filled, the dosage reads 5g of medicine, did the pharmacist make a mistake?
Skip to main content. Module 3: Measurement. Search for:. Convert from one temperature scale to the other, using conversion formulas. Try It Which of the following sets of three units are all metric measurements of length? A inch, foot, yard B kilometer, centimeter, millimeter C kilogram, gram, centigram D kilometer, foot, decimeter Show Solution B kilometer, centimeter, millimeter All of these measurements are from the metric system.
Example How many milligrams are in one decigram? Show Solution Identify locations of milligrams and decigrams. Dg is 10 times larger than a cg, and a cg is 10 times larger than a mg. Try It Convert 3, milligrams to grams. Show Solution One gram is 1, times larger than a milligram, so you can move the decimal point in 3, three places to the left.
Example Convert 1 centimeter to kilometers. Show Solution Identify locations of kilometers and centimeters. Cm is 10 times smaller than a dm; a dm is 10 times smaller than a m, etc. The kilo- is three prefixes before the base unit, so you would move the decimal three places to the left.
Move the decimal to the left if you're converting smaller units into larger ones. Move it to the right if you're converting larger units into smaller ones. Add zeros if necessary to fill in the spaces. The decimal was originally behind the "5," then you moved it three spaces to the right. Different base units also are related to each other. For example, one liter is equal to one kilogram. Be careful here — while the kilogram is considered the base unit to express mass in certain contexts, such as the mass or weight of a human being, the gram is still considered the base unit for mass or weight.
Method 2. Avoid converting between metric and non-metric units. If you want to truly understand the metric system, think of metric measurements as existing in your brain alongside Imperial measurements as two independent things.
If you learn a second language, you can learn by translating words and phrases from the second language into your first language, but to really understand the second language you have to learn to think in that language also. Instead of viewing metric measures as a "translation" of Imperial measurements, think about how you originally learned Imperial measurements.
You know how much a gallon is because you've seen gallon jugs of milk all your life. You can start thinking metrically the same way. Identify reference objects.
You probably got a basic idea of different weights and measures using the Imperial system by equating them to the size of things you saw every day. You can use the same principles to better understand the metric system. An egg weighs about 50 grams. For volume, think about the size of a liter bottle of soft drink. Label items around your house.
To reinforce thinking in terms of meters instead of Imperial measurements, measure the size or weight of different items around your house. Start with items that you look at or use on a regular basis.
Over time, you'll come to associate that object with that measurement in your head. For example, suppose you have a cookie jar that is 40 centimeters tall. You label the cookie jar with the measurement. If someone mentions something being 50 centimeters long, you might have a good idea of how long that thing is because you can add another 10 centimeters to the image of the cookie jar in your head.
Find metric measures for familiar distances. Especially if you travel internationally, you'll need to understand kilometers and meters so you can find your way around.
Start by learning distances to places you frequent. For example, maybe you work at a store 12 kilometers from your house. If you're traveling overseas and you're told your hotel is 10 kilometers from the airport, you can compare that distance to the distance between your home and your job to decide whether you can walk that distance or need to call a cab. Use metric measurements in the kitchen. The kitchen can be one of the easiest places to start incorporating the metric system into your everyday life, especially if you do a lot of cooking.
Most cookbooks include both Imperial and metric measurements for ingredients. Replace all your measuring cups and spoons with their metric equivalents.
When you cook, use those measures exclusively — try not to think about what that amount would be under the Imperial measurement system.
Focus on metric measurements at the grocery store. The grocery store is another place where it's easy to work on thinking metrically, because most food packages include metric and Imperial measurements on the label. Method 3. Think in tens. The metric system simplifies units of measurement by converting between larger and smaller units using multiples of ten. Each larger unit is exactly 10 times larger than the previous unit.
For example, there are 12 inches in a foot. To convert feet to inches, you must multiply by However, since the metric system is arranged in multiples of ten, there's no complex math involved in converting metric measurements.
Learn the order of the prefixes.
