IMPERIAL MEASUREMENTS

Length, Mass, Capacity, and Temperature

Two Systems

Metric

•Used in the scientific community

•Easily works with decimals

•Used by most countries as the standard system

Imperial

•Used in industry•Uses fractions•Used by the United States, Myanmar (Burma), and Liberia

Measurements of Length

•Inches•Feet•Yards•Miles

12 Inches = 1 foot3 feet = 1 yard1760 yards = 1 mile

Because you are writing the Canadian version of

the GED, you do not need to memorize these

conversion. You only need to be able to

convert them if asked to.

Using the Conversions

The best way is to use a proportion:

1. Set up the conversion scale

2. Match your new information by units with the scale

3. Cross – Multiply and Divide!

Once you’re comfortable with the conversions,

you can skip to JUST multiply or divide.

Example:

How many inches are in 5 feet?

12 inches = 1 foot

=

Example:

How many feet are in 3 yards?

3 feet = 1 yard

=

Example:

How many yards are in 1.5 miles?

1760 yards = 1 mile

=

Example:

How many feet are in 301 inches?

12 inches = 1 foot

=

Note: When using the imperial system, you usually use a smaller unit to describe measures smaller than a single unit (instead of a

decimal).

Example:

How many yards are in 32 feet?

3 feet = 1 yard

=

Example:

How many miles are in 4500 yards?

1760 yards = 1 mile

=

Measurements of Capacity

•Ounce (fluid)

•Cup•Pint•Quarts•Gallon

8 ounces = 1 cup2 cups = 1 pint2 pints = 1 quart4 quarts = 1 gallon

Example:

How many ounces are in 3 cups?

8 ounces = 1 cup

=

Example:

How many cups are in 15 pints?

2 cups = 1 pint

=

Example:

How many pints are in 12 quarts?

2 pints = 1 quart

=

Example:

How many quarts are in 2 gallons?

4 quarts = 1 gallon

=

Example:

How many cups are in 30 ounces?

8 ounces = 1 cup

=

Example:

How many pints are in 20 cups?

2 cups = 1 pint

=

Example:

How many quarts are in 50 pints?

2 pints = 1 quart

=

Example:

How many gallons are in 22 quarts?

4 quarts = 1 gallon

=

Measurements of Mass

•Ounce•Pounds•Ton

16 ounces = 1 pound2000 pounds = 1 ton

Example:

How many pounds are in 30 ounces?

16 ounces = 1 pound

=

Example:

How many tons are in 20 000 pounds?

2000 pounds = 1 ton

=

Example:

How many ounces are in 135 pounds?

16 ounces = 1 pound

=

Example:

How many pounds are in 2 tons?

2000 pounds = 1 ton

=

Measurements of Temperature

Only one:•Fahrenheit

° 𝐹=°𝐶×95+32Note: There’s no simple step for Fahrenheit

to Celsius because they are from two different systems. Instead of a proportion,

you’re going to have to use good ol’ ALGEBRA.

Example:

What is 0 in ?

° 𝐹=°𝐶×95+32

Example:

What is 20 in ?

° 𝐹=°𝐶×95+32

Example:

What is 60 in ?

° 𝐹=°𝐶×95+32

Example:

What is 10 in ?

° 𝐹=°𝐶×95+32
