Choosing Appropriate Units of Measurement Worksheets

For most values that express a value of a quantity in is necessary to use a unit of measure to communicate a clear understanding of what you are referring to. The other day one of my colleague told me that he was running 5 every other day. As an avid runner, I assumed he was getting in really good shape because he was running 5 miles every other day. He was really referring to the number of laps he was running in the school gym. This is the equivalent to just over 1/4 mile. That is a significant difference. This is just a simple example of how making sure that you not only pick accurate units for yourself, but also to communicate your message to others. These worksheets and lessons help students identify the proper units to satisfy the word problems they are solving.

How to Make Sure You Choose Appropriate Units in?

Using the right units is a crucial step when solving numerical problems. Units give a number a meaning and help us understand exactly what it represents. A number without a unit does not hold any meaning. For instance, you ask a salesperson at a carpet store what size will be best for a rug that you need to place under your living room's center table, and he replies with "55." Now, what is 55? Is it a square inch? Square feet? Or square meters? Yes, we can apply some common sense, but for someone who does not know much, he will have no clue what the salesperson is saying.

So, how to choose appropriate units for just about unit of measurement? It all begins with understanding the different units that are associated with certain quantities. It also depends on local surroundings if you are in a country that use the metric system, metric units apply. Otherwise, Customary Imperial units apply. The most commonly used measurements and their units are:

Length (metric): kilometers (km), meters (m), centimeters (cm), millimeters (mm)

Length (customary): inch (in), foot (ft), yard (yd), mile (mi)

Mass (metric): gram (g), kilogram (kg), ton (t), milligram (mg)

Mass (customary): ounce (oz), pound (lb), ton (tn)

Capacity (metric): liter (l), milliliter (ml), cubic centimeter (cc)

Time: second (sec), minute (min), hour (hr), day (d), month (mo), year (yr)

Once you have a sense of these units it is time to apply them to your daily situation. The first thing you need to do is understand the type of measure that you are referring to. Is it a measure of distance from end to end (length)? Is it the downward force that an object exerts (weight)? Is it how much something can hold (capacity)? Now you can be applying units to it. Once you have identified the units, check whether all quantities have the same units or not. If the units are not the same, you need to carry out conversions. Only when you have converted all units, you can perform the operation the numerical is asking you to carry out.
