## 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 470 kilometers into millimeters we have to multiply 470 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

470 km → L(mm)

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

L(mm) = 470 km × 1000000 mm

L(mm) = 470000000 mm

The final result is:

470 km → 470000000 mm

We conclude that 470 kilometers is equivalent to 470000000 millimeters:

470 kilometers = 470000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 2.1276595744681E-9 × 470 kilometers.

Another way is saying that 470 kilometers is equal to 1 ÷ 2.1276595744681E-9 millimeters.

## Approximate result

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

470 km ≅ 470000000 mm

An alternative is also that one millimeter is approximately zero times four hundred seventy kilometers.
