LecturePLUS Timberlake

State the same measurement in two different units

length

10.0 in.

25.4 cm

LecturePLUS Timberlake

Length

1 m = 100 cm

Mass

1 kg = 1000 g

Volume

1 L=1000 mL

LecturePLUS Timberlake

A. 1000 m = 1 ___1) mm 2) km3) dm

B. 0.001 g = 1 ___ 1) mg2) kg3) dg

C. 0.1 L = 1 ___1) mL2) cL3) dL

D. 0.01 m = 1 ___ 1) mm 2) cm3) dm

LecturePLUS Timberlake

A. 1000 m = 1 ___2) km

B. 0.001 g = 1 ___ 1) mg

C. 0.1 L = 1 ___3) dL

D. 0.01 m = 1 ___ 2) cm

LecturePLUS Timberlake

Give the value of the following units:

A. 1 kg = ____ g

1) 10 g2) 100 g 3) 1000 g

B. 1 mm = ____ m

1) 0.001 m2) 0.01 m 3) 0.1 m

LecturePLUS Timberlake

A. 1 kg = ____ g

3) 1000 g

B. 1 mm = ____ m

1) 0.001 m

LecturePLUS Timberlake

1 ft= inches

1 lb=16 oz

1 quart = pints

1 quart=4 cups

Why are the quantities in each pair equal?

LecturePLUS Timberlake

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

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

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

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.

LecturePLUS Timberlake

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

A. quarts and mL 1 L = 1000 mL

1 L and 1000 mL

1000 mL 1 L

B. hours and minutes1 hr = 60 min

1 hr and 60 min

60 min1 hr

C. meters and kilometers 1 km = 1000 m

1 km and 1000 m

1000 m 1 km
