How many kilometers are there in 15 millimetres?

Answer 1

There are 1000 x 1000 = 1000000 millimetres in one kilometre.

Therefore, 15 millimetres is equal to 15/1000000 = 0.000015 kilometres.

15 mm = 15 x 10-6 km

Answer 2

One kilometre is equal to 1000 x 1000 = 1000000 millimetres. Therefore, 15 kilometres is equal to 15 x 1000000 = 15000000 millimetres.

Answer 3

There are 1000 x 1000 = 1000000 millimetres in one kilometre. Therefore, 1.5 millimetres is equal to 1.5/1000000 = 0.0000015 kilometres.
