Prefixes and

Equalities

LecturePLUS Timberlake


Metric prefixes l.jpg
Metric Prefixes

  • Increase or decrease basic unit by 10

  • Form new units larger or smaller than the basic units

  • Indicate a numerical value

    prefix = value

    1 kilometer = 1000 meters

    1 kilogram = 1000 grams

Some american equalities l.jpg
Some American Equalities

1 ft = inches

1 lb = 16 oz

1 quart = pints

1 quart = 4 cups

Why are the quantities in each pair equal?

LecturePLUS Timberlake


Some american equalities18 l.jpg
Some American Equalities

1 ft = 12 inches

1 lb = 16 oz

1 quart = 2 pints

1 quart = 4 cups

The quantities in each pair give the same measured amount in two different units.

LecturePLUS Timberlake


Some metric american equalities l.jpg
Some Metric-American Equalities

1 in. = 2.54 cm

1 qt = 946 mL

1 L = 1.06 qt

1 lb = 454 g

1 kg = 2.20 lb

Remember these for exams.

LecturePLUS Timberlake


Equalities given in a problem l.jpg
Equalities given in a Problem

Example 1

At the store, the price of one pound of red peppers is $2.39.

Equality: 1 lb red peppers = $2.39

Example 2

At the gas station, one gallon of gas is $1.34.

Equality: 1 gallon of gas = $1.34

LecturePLUS Timberlake


Conversion factors l.jpg
Conversion Factors

Fractions in which the numerator and denominator are quantities expressed in an equality between those units

Example: 1 in. = 2.54 cm

Factors: 1 in. and 2.54 cm

2.54 cm 1 in.

Write conversion factors that relate each of the following pairs of units:

A. Liters and mL

B. Hours and minutes

D. Meters and kilometers

LecturePLUS Timberlake


Solution23 l.jpg
Solution

A. quarts and mL 1 L = 1000 mL

1 L and 1000 mL

1000 mL 1 L

B. hours and minutes 1 hr = 60 min

1 hr and 60 min

60 min 1 hr

C. meters and kilometers 1 km = 1000 m

1 km and 1000 m

1000 m 1 km
