31. 735 cm = ? Liters 3 735 cm X 1 mL X __1 L__ = 735 L = .735 L 3 1 1 cm 1000 mL 1000

22 2. 98 m = ? micrometers

2298 m X 1,000,000 µm X 1,000,000 µm = 98,000,000,000,000 µm

1 1 m 1 m

3. 48 gal = ? mL

48 gal X 3.7 L X 1000 mL = 177,600 mL

1 1 gal 1 L

33 4. 876 yards = ? mm

3876 yd X _3 ft_ X _3 ft_ X _3 ft_ X 30.5 cm X 30.5 cm X 30.5 cm

1 1 yd 1 yd 1 yd 1 ft 1 ft 1 ft

113 X 10 mm X 10 mm X 10 mm = 6.71 X 10 mm

1 cm 1 cm 1cm

5. 45 kg = ? lbs

45 kg X 1000 g X _1 lb_ = 45000 lb = 99.12 lbs

1 1 kg 454 g 454

226. 45 mm = ? in

22 45 mm X _1 cm_ X _1 cm_ X __1 in__ X __1 in__ = .0698 in

1 10 mm 10 mm 2.54 cm 2.54 cm

37. 62.4 lbs/ft = g/mL

3 62.4 lb X 454 g X __1 ft__ X __1ft__ X __1 ft__ X 1 cm= .998g/mL 3 1 ft 1 lb 30.5 cm 30.5 cm 30.5 cm 1 mL

8. 90 km/hr = miles/sec

90 km X _1 mi_ X _1 hr_ X _1 min_ = _90 mi_ = .015625 mi/s

1 hr 1.6 km 60 min 60 sec 5760 s

229. 23.4 lbs/in = ? g/km

23.4 lb X 454 g X __1 in__ X __1 in__ X 100 cm X 100 cm X 2 1 in 1 lb 2.54 cm 2.54 cm 1 m 1 m

13 2 1000 m X 1000 m = 1.647 X 10g/km

1 km 1 km
