## 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 330 kilometers into millimeters we have to multiply 330 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

330 km → L(mm)

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

L(mm) = 330 km × 1000000 mm

L(mm) = 330000000 mm

The final result is:

330 km → 330000000 mm

We conclude that 330 kilometers is equivalent to 330000000 millimeters:

330 kilometers = 330000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 3.030303030303E-9 × 330 kilometers.

Another way is saying that 330 kilometers is equal to 1 ÷ 3.030303030303E-9 millimeters.

## Approximate result

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

330 km ≅ 330000000 mm

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