50 mm equals how many km?

Answer 1

All you need to to is remember 1Km = 1000m and 1m = 1000mm

so mm expressed as meters is 50 divided by 1000 = 0.05m

and 0.05m in Km we have to devide by 1000 again so that's = 0.00005Km

so 50mm = 0.00005Km

Answer 2

1 km = 1000 meters = 106 millimeter

Answer = 50 km = 50 x 106 mm or 50 million millimeter

Answer 3

50 mm is equal to 0.05 km.
