Unit conversion word problems (ACT) Practice Questions (Grade 9)

Question 1easy

A hiking trail segment is $5$ yards long. What is the length of the segment in inches?
(Note: $1$ yard $= 3$ feet and $1$ foot $= 12$ inches)

Multiply by conversion factors so the old units cancel: $5\,\text{yd} \times \dfrac{3\,\text{ft}}{1\,\text{yd}} \times \dfrac{12\,\text{in}}{1\,\text{ft}} = 180\,\text{in}$ .

Question 2easy

A film festival runs for $2$ days. How many minutes long is the festival?
(Note: $1$ day $= 24$ hours and $1$ hour $= 60$ minutes)

Multiply by conversion factors so the old units cancel: $2\,\text{days} \times \dfrac{24\,\text{h}}{1\,\text{day}} \times \dfrac{60\,\text{min}}{1\,\text{h}} = 2{,}880\,\text{min}$ .

Question 3easy

A package weighs $4$ pounds. What is the weight of the package in ounces?
(Note: $1$ pound $= 16$ ounces)

Multiply by a conversion factor so the old unit cancels: $4\,\text{lb} \times \dfrac{16\,\text{oz}}{1\,\text{lb}} = 64\,\text{oz}$ .

Question 4easy

A running track is $2$ kilometers long. What is the length of the track in meters?
(Note: $1$ kilometer $= 1{,}000$ meters)

Multiply by a conversion factor so the old unit cancels: $2\,\text{km} \times \dfrac{1{,}000\,\text{m}}{1\,\text{km}} = 2{,}000\,\text{m}$ .

Question 5easy

A bottle holds $3$ liters of water. How many milliliters of water is that?
(Note: $1$ liter $= 1{,}000$ milliliters)

Multiply by a conversion factor so the old unit cancels: $3\,\text{L} \times \dfrac{1{,}000\,\text{mL}}{1\,\text{L}} = 3{,}000\,\text{mL}$ .

Question 6medium

A cooler holds $3$ gallons of juice. How many cups of juice is that?
(Note: $1$ gallon $= 4$ quarts and $1$ quart $= 4$ cups)

Multiply by conversion factors so the old units cancel: $3\,\text{gal} \times \dfrac{4\,\text{qt}}{1\,\text{gal}} \times \dfrac{4\,\text{cups}}{1\,\text{qt}} = 48\,\text{cups}$ .

Question 7medium

A sprinter runs at a speed of $88$ feet per second. What is the sprinter's speed in miles per hour?
(Note: $1$ mile $= 5{,}280$ feet)

Multiply by conversion factors so the old units cancel: $88\,\dfrac{\text{ft}}{\text{s}} \times \dfrac{1\,\text{mi}}{5{,}280\,\text{ft}} \times \dfrac{3{,}600\,\text{s}}{1\,\text{h}} = 60\,\dfrac{\text{mi}}{\text{h}}$ .

Question 8medium

A drone is flying at a speed of $20$ meters per second. What is the drone's speed in kilometers per hour?
(Note: $1$ kilometer $= 1{,}000$ meters)

Multiply by conversion factors so the old units cancel: $20\,\dfrac{\text{m}}{\text{s}} \times \dfrac{1\,\text{km}}{1{,}000\,\text{m}} \times \dfrac{3{,}600\,\text{s}}{1\,\text{h}} = 72\,\dfrac{\text{km}}{\text{h}}$ .
