## 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 248 kilometers into millimeters we have to multiply 248 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

248 km → L(mm)

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

L(mm) = 248 km × 1000000 mm

L(mm) = 248000000 mm

The final result is:

248 km → 248000000 mm

We conclude that 248 kilometers is equivalent to 248000000 millimeters:

248 kilometers = 248000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 4.0322580645161E-9 × 248 kilometers.

Another way is saying that 248 kilometers is equal to 1 ÷ 4.0322580645161E-9 millimeters.

## Approximate result

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

248 km ≅ 248000000 mm

An alternative is also that one millimeter is approximately zero times two hundred forty-eight kilometers.
