Worksheet: Unit conversions, Exponential Notation, Sig Figs

To practice unit conversions the same way you’ll have to do on exam, use only metric prefix conversions and the following

1.000m3 = 1000L
1.000kg = 2.200lb
1qt = 2 pt
1 pt = 16 fl oz
1.00 fl oz = 29.6mL
1.000 lb = 16.00 oz

Perform following conversions:
1) 2.548 m =cm
2) 3.75 lb =g
3) 5.45 oz =kg
4) 0.23 Bq=mBq
5) 3.58 cm3=dm3
6) 0.035L=cL
7) 0.053mm=?m
8) 35.8 mg=kg
9) 56.0 cm=m
10) 258 g=lb
11) 32 fl oz=mL
12) 0.85kg=lb
13) 13.5L=m3
14) 0.050km=cm
15) 0.13kg=mg
16) 25.9 qt=L
17) 17.9 g =kg
18) 25.85 ?g =mg
19) 859 g = oz
20) 138 mL = qt

Perform following operations and provide result with correct number of significant figures 21) 2.50 * 2.000=
22) 1.35 + 0.0285=
23) 0.350 * 20. =
24) 0.450 ÷ 4.90=
25) 7.50 – 0.0045
26) 2.9 * 7 =
27) 2.35 ÷ 1.2 =
28) 0.85 + 121=
29) 55.9 – 4.5 =
30) 2.50 ÷ 84 =
31) 1.25x104 * 2.000x108 =
32) 3.8x104 – 2.000x103 =
33) 4.9x107 ÷ 3.200x10–8 =
34) 3.70x10–3 ? 2.0x105 =
35) 7.88x1022 ÷ 2.000x10–3
36) 3.8x104 + 2.000x103 =
37) 9.8x109 ? 2.0x105
38) 4.9x107 – 3.200x108 =
39) 3.8x1051 + 2.000x1053 =
40) 6.40x10–7 + 3.200x10–8

Convert the following numbers from decimal to exponential format or vice versa, as needed 41) 0.00054 =
42) 2500. =
43) 6585000 =
44) 3.585x104 =
45) 4.50x10–3 =
46) 1280 =
47) 6x105 =
48) 3x10–5 =
49) 0.00250
50) 5.0x10–3
