Convert the following units to their S.I units (i) 10g (ii)100mm(iii)250cm(v) 500mg and 20km

Answer 1

(i) 10g = 0.01 kg (since 1 kg = 1000 g)
(ii) 100mm = 0.1 m (since 1 m = 1000 mm)
(iii) 250cm = 2.5 m (since 1 m = 100 cm)
(iv) 500mg = 0.5 g (since 1 g = 1000 mg)
(v) 20km = 20000 m (since 1 km = 1000 m)
