5th Grade Converting Measurement Units Test Solutions and Scoring (PDF)

1. \(6\times3=18\), so 18 ft
2. \(64\div16=4\), so 4 lb

Scoring: 1 point for each correct conversion with unit.

1. \(5\times1{,}000=5{,}000\), so 5,000 mL
2. \(3{,}200\div1{,}000=3.2\), so 3.2 kg

Scoring: 1 point for each correct conversion with unit.

1 gal = 4 qt = 8 pt = 16 c. So \(3\times16=48\) cups.

48 cups

Scoring: 1 point for using 16 cups in a gallon (or the chain 4, 2, 2), 1 point for 48 cups.

1. \(5\text{ ft}=60\text{ in}\), and \(60>58\), so \(5\text{ ft}>58\text{ in}\)
2. \(2\text{ kg}=2{,}000\text{ g}\), and \(2{,}000<2{,}500\), so \(2\text{ kg}<2{,}500\text{ g}\)

Scoring: 1 point for each correct comparison supported by a conversion.

Each foot is 12 in. \(40\div12=3\) with a remainder of 4. So 3 feet use 36 inches and 4 inches are left.

3 ft 4 in

Scoring: 1 point for dividing by 12, 1 point for the answer 3 ft 4 in.

2.5 kg = \(2.5\times1{,}000=2{,}500\) g. Then \(2{,}500-750=1{,}750\).

1,750 g

Scoring: 1 point for converting kilograms to grams, 1 point for subtracting correctly.

7,920 ft = \(7{,}920\div5{,}280=1.5\) mi. Total: \(3+1.5=4.5\) mi.

4.5 miles

Scoring: 1 point for converting feet to miles, 1 point for the total.

1. \(3\times4=12\) cups
2. \(12\div2=6\) pints
3. 12 cups = 3 quarts, so 3 cartons

Scoring: 1 point per part.

1. \(2\times16+4=36\) oz
2. \(6\times5=30\) oz
3. \(36-30=6\) oz

Scoring: 1 point per part.
