Introduction
Why Should I Use This Book?
This book was created to provide you with targeted review and practice in
the most essential measurement and conversions skills. It provides 501
problems to help solidify your understanding of a variety of concepts. 501
Measurement and Conversion Questions is designed for many audiences,
because measurement and conversion questions are not just found in the
classroom or on standardized tests, they abound in every aspect of life and
in virtually every profession. If you plan on entering one of the trades, you
know how critical good measurement and conversion skills are, but did you
know that these skills are just as essential for being a firefighter, a busi-
nessperson, a cashier, or a nurse? And the list goes on and on. In addition,
having a solid grasp of the knowledge contained in this book is fundamen-
tal to scoring higher on the math portions of the SAT, ACT, GRE, or on a
vocational or professional exam. And of course, 501 Measurement and Con-
version Questionsis great for anyone who has ever taken a math course and
wants to refresh and revive forgotten skills. Or, it can be used to supplement
current instruction in a math class.

501 Measurement and Conversion Questions
How to Use This Book
First, look at the table of contents to see the types of measurement and con-
version topics covered in this book. The book is organized into four meas-
urement chapters and six conversion chapters. The measurements chapters
are Perimeter, Area, Volume, and Angles and Arc. The conversion chapters
are Dollars and Cents; Fractions, Decimals, and Percents; Scientific Nota-
tion and Decimals; Metric and Standard Units: Length, Area, and Volume;
and Metric and Standard Units: Temperature and Weight. The structure of
these chapters follows a common sequence of math concepts. You may want
to follow the sequence because the concepts grow more advanced as the
book progresses. However, if your skills are just rusty, or if you are using this
book to supplement topics you are currently learning, you may want to jump
around from topic to topic.
As you complete the problems in this book, you will undoubtedly want to
check your answers against the answer explanation section at the end of each
chapter. Every problem in 501 Measurement and Conversion Questions has a
complete answer explanation. For problems that require numerous steps, a
thorough step-by-step explanation is provided. This will help you under-
stand the problem-solving process. The purpose of drill and skill practice is
to make you proficient at solving problems. Like an athlete preparing for the
next season or a musician warming up for a concert, you become more skill-
ful with practice. If, after completing all the problems in a section, you feel
you need more practice, do the problems over. It’s not the answer that mat-
ters most—it’s the process and the reasoning skills that you want to master.
You will probably want to have a calculator handy as you work through
some of the sections. It’s always a good idea to use it to check your calcula-
tions, and don’t forget to keep lots of scrap paper on hand.
Make a Commitment
Success does not come without effort. Make the commitment to improve
your measurement and conversion skills, and work for understanding. Why
you do a problem is as important as how you do it. If you truly want to be
successful, make a commitment to spend the time you need to do a good
job. You can do it! When you achieve measurement and conversion success,
you have laid the foundation for future challenges and success. So sharpen
your pencil and practice!

Measurement—
Perimeter
This chapter starts with the most basic of the measurements—perime-
ter. These are problems that involve measuring the distance around a geo-
metric shape. You can think of perimeter as being a boundary for a polygon.
Circumference is the name given to the perimeter of a circle. Study the for-
mulas before moving on to working the problems in this section. Remem-
ber that perimeter is an addition concept. Read each question carefully and
always double check your answer. When you finish, carefully read over the
answer explanations.

Formulas
To find the perimeter of any object, add the lengths of all sides of the object.
Square with side length s

P= s+ s+ s+ s
Rectangle with length l and width w

P= l+ l+w+ w
Circle with diameter d
Note: The distance around a circle is called the circumference rather than
the perimeter.
