## 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 318 kilometers into millimeters we have to multiply 318 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

318 km → L(mm)

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

L(mm) = 318 km × 1000000 mm

L(mm) = 318000000 mm

The final result is:

318 km → 318000000 mm

We conclude that 318 kilometers is equivalent to 318000000 millimeters:

318 kilometers = 318000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 3.1446540880503E-9 × 318 kilometers.

Another way is saying that 318 kilometers is equal to 1 ÷ 3.1446540880503E-9 millimeters.

## Approximate result

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

318 km ≅ 318000000 mm

An alternative is also that one millimeter is approximately zero times three hundred eighteen kilometers.
