1) Please convert the following:
a) The height of Mount Everest is 29,035 feet. How many miles is that?
29035 ft 1 mi
x ≈ 5.5miles
1 5280 feet
b) You run a 10 kilometer race. How many miles did you run?
10 km 0.621mi
x =6.21miles
1 1 km
c) You buy a 24 pack of 591mL bottles of water. How many Liters is that?
24 ×591 mL=14184 mL
Using the metric to metric conversions kL hL daL L dL cL mL
This is 3 jumps to the left, which results in 14.184 L
2) How many pints are in 15 gallons?
15 gallons 4 quarts 2 pints
× × =120 pints
1 1 gal 1 qt
3) Earlier this year in a drug bust in Shanghai, China, police seized 2.4 tons of
methamphetamines. If a typical dosage is 50mg, how many doses is that drug bust, which the
Chinese police prevented from being sold to the public?
We need to get to milligrams, which is metric, but have tons, which is English. 2.4 tons must
be converted to pounds first and then kilograms and then to milligrams.
2.4 tons 2000lbs 1 kg ≈ 2182 kg
× ×
, 1 1 ton 2.2lbs
Using the metric to metric conversions kg hg dag g dg cg mg
This is 6 jumps to the right, which yields: 2,182,000,000mg
Now we convert this to doses, knowing that 1 dose = 50mg…
2,182,000,000 mg 1 dose
× =43,640,000 doses
1 50 mg
4) The low temperature today is 20°F. What would this be in Celsius?
5 5 5
C= ( F−32)= (20−32)= (−12) ≈−6.7℃
9 9 9
This makes sense, since we know that 0°C is freezing, and 20°F is below freezing.
5) A 52 inch wide TV has a screen area of 1,064 in2. How many square feet is that?
52 inch is extraneous information. Because of Square unit, we must either use the conversion
1064 ¿2 1 ft2 2
12∈¿𝗏
x 2 =7.39 ft
1 1 ft¿
144
twice, or square it to cancel out in2 12∈¿ x ¿

6) Water is coming out of a hose at 20 quarts per minute, how many gallons per hour is this?
Remember per minute, means the minute unit is in the bottom, you can also set this up in 2
20 qt 1 gal 60 min
order does n' tmatter . x x =300 gal / hr
steps and the 1 min 4 qt 1 hr
7) You are constructing a rectangular concrete patio that measures 10 feet long, 6 feet wide
and 10 inches deep. What is the volume in ft3? What is the volume in m3? First make 10 in
5
12∈¿= ft𝗏.83 ft

8) You order a 1 pound steak in Indianapolis, but pounds are not used in Australia. Please
convert pounds to ounces, then to grams so you can order steak in Australia. 1 ounce = 28
28 grams
1 pound 16 oz x =448 grams
