## Conversion formula

The conversion factor from kilometers to millimeters is 1000000, which means that 1 kilometer is equal to 1000000 millimeters:

1 km = 1000000 mm

To convert 506 kilometers into millimeters we have to multiply 506 by the conversion factor in order to get the length amount from kilometers to millimeters. We can also form a simple proportion to calculate the result:

1 km → 1000000 mm

506 km → L(mm)

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

L(mm) = 506 km × 1000000 mm

L(mm) = 506000000 mm

The final result is:

506 km → 506000000 mm

We conclude that 506 kilometers is equivalent to 506000000 millimeters:

506 kilometers = 506000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 1.9762845849802E-9 × 506 kilometers.

Another way is saying that 506 kilometers is equal to 1 ÷ 1.9762845849802E-9 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that five hundred six kilometers is approximately five hundred six million millimeters:

506 km ≅ 506000000 mm

An alternative is also that one millimeter is approximately zero times five hundred six kilometers.
