What does it mean to measure?
Welcome to the world of measurement! In this lesson, you will begin to explore the questions "What can be measured?" and "What does it mean to measure something?" You will identify measurable properties of objects such as length, capacity, and weight, and discuss which customary units are appropriate for measuring these properties.

Review
Length
•
Length
is a measure how long something is from end to end. This may also include
distance
, which is defined as the space between points or objects. When you measure the
distance
around an object, you are finding its
perimeter
. We use units to measure both length and distance. There are two systems of measurement: the Metric System and U.S. Customary Units. • • •
When To Use Which Unit
To measure very short lengths, such as the length of your big toe or a strand of hair, we usually use inches. When we want to measure somewhat longer lengths or distances, we usually use feet, or yards. Some examples would be the height of a fence or the length of a basketball court. For measuring longer distances, we use miles, such as the distance from your house to your school or the height of a volcano.

Weight & Capacity
Weight
is the amount of matter in an object. A
scale
used to measure weight.
is a device • When you measure the
weight
of a very small object, such as a leaf, the best unit to use is a fraction of an
ounce
.
• The
weight
of a larger object, such as an orange, is measured using
ounces
.
• Large objects, such as a person, can be measured using
pounds
.
• When measuring even bigger objects, like a hippopotamus, the best units to use are
tons.
Weight & Capacity
• • •
Capacity answers the question, "How much does it hold.“
Within the customary system, the common units for measuring capacity are fluid ounces, cups, pints, quarts, and gallons.
A regular cup of coffee is about one cup. A large milk container is about a gallon.

Selecting the Right Measure
It’s important to choose the right unit when measuring. While you could measure the distance from your house to school in inches, it would be easier to measure the distance in miles.
It’s also important to know which tool to use when you are measuring objects. For example, it would be pretty hard to measure how much pop your glass can hold with a ruler.

Converting Measures
• • In problems which involve measurements such as length, weight, and capacity, it is often necessary to convert from one measurement unit to another. To go from a larger unit to a smaller unit, MULTIPLY.
To go from a smaller unit to a larger unit, DIVIDE.
Follow the three basic steps 1.
Look to see whether you are going from larger to smaller units (multiply), or smaller to larger units (divide).
2.
3.
Figure out how many of the smaller units are in one of the larger units.
Calculate the conversion.

Converting Measures
Equivalent measures from cups to gallons is shown here. There are 4 quarts in each gallon. There are 2 pints in each quart. There are 2 cups in each pint. That means that there are 16 cups in each gallon!
