Unit Review: Units of measurement

N.1Fill in the missing number. 1 ft = 12 in, 1 yd = 3 ft, 1 lb = 16 oz, 1 gal = 4 qt, 1 qt = 2 pt, 1 pt = 2 c.

1. 1
   $8\text{ qt}=$ $\boxed{}\text{ pt}$
2. 2
   $24\text{ c}=$ $\boxed{}\text{ qt}$
3. 3
   $2\text{ pt}=$ $\boxed{}\text{ c}$
4. 4
   $8\text{ pt}=$ $\boxed{}\text{ qt}$

N.2Add or subtract. Regroup when you need to.

1. 5
   $3\text{ yd}21\text{ in}+1\text{ yd}18\text{ in}=$ $\boxed{}\text{ yd}\boxed{}\text{ in}$
2. 6
   $8\text{ yd}2\text{ ft}-3\text{ yd}1\text{ ft}=$ $\boxed{}\text{ yd}\boxed{}\text{ ft}$
3. 7
   $1\text{ gal}2\text{ qt}+6\text{ gal}1\text{ qt}=$ $\boxed{}\text{ gal}\boxed{}\text{ qt}$
4. 8
   $4\text{ ft}5\text{ in}+2\text{ ft}8\text{ in}=$ $\boxed{}\text{ ft}\boxed{}\text{ in}$

N.3Fill in each box. 1 km = 1,000 m · 1 m = 100 cm · 1 cm = 10 mm · 1 kg = 1,000 g · 1 L = 1,000 mL

1. 9
   $7.7\text{ cm}=$ $\boxed{}\text{ mm}$
2. 10
   $6.3\text{ m}=$ $\boxed{}\text{ cm}$
3. 11
   $3.41\text{ kg}=$ $\boxed{}\text{ g}$
4. 12
   $8.18\text{ m}=$ $\boxed{}\text{ mm}$

N.4Use 1 in = 2.54 cm, 1 mi ≈ 1.61 km, 1 kg ≈ 2.2 lb and 1 gal ≈ 3.79 L. Round to the nearest tenth.

1. 13
   $4\text{ in}\approx \boxed{}\text{ cm}$
2. 14
   $35\text{ in}\approx \boxed{}\text{ cm}$
3. 15
   $44\text{ lb}\approx \boxed{}\text{ kg}$
4. 16
   $35\text{ lb}\approx \boxed{}\text{ kg}$

N.5Use F = 1.8C + 32 and C = (F − 32) ÷ 1.8. Round to the nearest tenth if needed.

1. 17
   $131^{\circ }\text{F}=$ ${\boxed{}}^{\circ }\text{C}$
2. 18
   $55^{\circ }\text{C}=$ ${\boxed{}}^{\circ }\text{F}$
3. 19
   $77^{\circ }\text{F}=$ ${\boxed{}}^{\circ }\text{C}$
4. 20
   $30^{\circ }\text{C}=$ ${\boxed{}}^{\circ }\text{F}$
