U.1 La medida de las magnitudes

A.6 Expresando medidas en unidades básicas

12 hm = 12 · 102 m = 1200 m

16 km = 16 · 103 m = 16000 m

60 cm = 60 · 10–2 m = 0,60 m

160 mm = 160 · 10–3 m = 0,160 m

6 t = 6 · 103 kg = 6000 kg

4000 g = 4000 · 10–3 kg = 4 kg

720 mg = 720 · 10–6 kg = 0,000 720 kg

0,8 dag = 0,8 · 10-2 kg = 0,008 kg

800 cm2 = 800 · 10–4 m2 = 0,08 m2

14 hm2 = 14 · 104 m2 = 140000 m2

80 m2 = 80 m2

200 dm2 = 200 · 10–2 m2 = 2 m2

3000 cm3 = 3000 · 10–6 m3 = 0,003 m3

60 mm3 = 60 · 10–9 m3 = 0,000 000 06 m3

0,06 dam3 = 0,06 · 103 m3 = 60 m3

5 m3 = 5 m3

180 mL = 180 cm3 = 180 · 10–6 m3 = 0,000 18 m3

24 cL = 24 · 10–2 L = 24 · 10–2 dm3 = 24 ·10-2 · 10–3 m3 =

0,000 24 m3

10 L = 10 dm3 = 10 · 10–3 m3 = 0,01 m3

2,5 hL = 2,5 · 102 L = 2,5 · 102 dm3 = 2,5 · 102 · 10–3 m3 =

2,5 · 10–1 m3= 0,25 m3
