5th Grade Converting Measurement Units Quiz: 10 Questions with Explanations

A 36 ftB 9 ftC 1 ftD 12 ft

1 yard = 3 feet, so \(3 \times 3 = 9\). Using 12 mixes up feet and inches.

A 80 ozB 50 ozC 60 ozD 160 oz

1 pound = 16 ounces, so \(5 \times 16 = 80\).

A 4 pintsB 8 pintsC 16 pintsD 2 pints

A gallon has 4 quarts and each quart has 2 pints, so \(4 \times 2 = 8\). Sixteen is the number of cups.

A 45 LB 4.5 LC 0.45 LD 4,500 L

1 L = 1,000 mL, so divide by 1,000 and get 4.5 L.

A 2 mB 190 cmC 0.0018 kmD 2,100 mm

In meters the lengths are 2.1, 2, 1.9 and 1.8, so 2,100 mm is longest.

A 2 ft 3 inB 3 ft 6 inC 2 ft 6 inD 30 ft

\(30 \div 12 = 2\) with 6 left over, so 2 ft 6 in.

A 2,000 lbB 400 lbC 4,000 lbD 40,000 lb

1 ton = 2,000 pounds, so \(2 \times 2{,}000 = 4{,}000\).

A 1,800 mB 2,800 mC 180 mD 18,000 m

5 km = 5,000 m, and \(5{,}000 – 3{,}200 = 1{,}800\).

A 30 qtB 3.75 qtC 7 qtD 7.5 qt

2 pints make 1 quart, so divide: \(15 \div 2 = 7.5\). Multiplying gives 30, which is wrong.

A 12 cupsB 6 cupsC 24 cupsD 48 cups

1 quart = 4 cups, so \(3 \times 4 = 12\).
