Expressing from Higher Unit to Lower Unit -
1) Express in 'm' :-
a) 1.5 km
1 km = 1000 m
1.5 km = 1.5 × 1000 m = 1500 m
b) 0.75 km
1 km = 1000 m
0.5 km = 0.75 × 1000 m = 750 m
2) Express in 'cm' :-
a) 0.15 m
1 m = 100 cm
0.15 m = 0.15 × 100 cm = 15 cm
b) 8.008 m
1 m = 100 cm
8.008 m = 8.008 × 100 cm = 800.8 cm
