pychu [463]

Answer:

0.004012km

Explanation:

Problem:

Conversion of millimeters(mm) to Kilometers:

value given = 4012mm

Here, we are converting from a submultiple unit to a multiple unit.

Millimeter depicts 10⁻³m and kilometer stands for 10³m

Now, we must find how many exponents will take us from 10⁻³ to  10³

careful examination shows that if we multiply a power of 10⁶ to 10⁻³ it will give a 10³:

   i.e 10⁻³ x 10⁶ = 10⁻³⁺⁶ = 10³

Therefore,

       10⁶mm = 1km

      4,012mm = \frac{4012}{1000000} = 0.004012km
