Conversion formula

The conversion factor from millimeters to kilometers is 1.0E-6, which means that 1 millimeter is equal to 1.0E-6 kilometers:

1 mm = 1.0E-6 km

To convert 1001 millimeters into kilometers we have to multiply 1001 by the conversion factor in order to get the length amount from millimeters to kilometers. We can also form a simple proportion to calculate the result:

1 mm → 1.0E-6 km

1001 mm → L_(km)

Solve the above proportion to obtain the length L in kilometers:

L_(km) = 1001 mm × 1.0E-6 km

L_(km) = 0.001001 km

The final result is:

1001 mm → 0.001001 km

We conclude that 1001 millimeters is equivalent to 0.001001 kilometers:

1001 millimeters = 0.001001 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 999.000999001 × 1001 millimeters.

Another way is saying that 1001 millimeters is equal to 1 ÷ 999.000999001 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that one thousand one millimeters is approximately zero point zero zero one kilometers:

1001 mm ≅ 0.001 km

An alternative is also that one kilometer is approximately nine hundred ninety-nine point zero zero one times one thousand one millimeters.
