Question

convert the following from smaller unit to bigger unit 200 mm in km

Answer 1

200/1000000=0.0002km

Answer 2

hey here is your language
===========================
1 km = 1000 m
and 1 m = 1000 mm
therefore ,

1 km = 1000 × 1000 mm
1 km = 1000000 mm
1 mm = 1/1000000 km

now,
200 mm = 200 × 1/1000000 km
= 2 × 10^ -4 km
