## 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 84 kilometers into millimeters we have to multiply 84 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

84 km → L(mm)

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

L(mm) = 84 km × 1000000 mm

L(mm) = 84000000 mm

The final result is:

84 km → 84000000 mm

We conclude that 84 kilometers is equivalent to 84000000 millimeters:

84 kilometers = 84000000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 1.1904761904762E-8 × 84 kilometers.

Another way is saying that 84 kilometers is equal to 1 ÷ 1.1904761904762E-8 millimeters.

## Approximate result

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

84 km ≅ 84000000 mm

An alternative is also that one millimeter is approximately zero times eighty-four kilometers.
