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 2.4 kilometers into millimeters we have to multiply 2.4 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

2.4 km → L(mm)

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

L(mm) = 2.4 km × 1000000 mm

L(mm) = 2400000 mm

The final result is:

2.4 km → 2400000 mm

We conclude that 2.4 kilometers is equivalent to 2400000 millimeters:

2.4 kilometers = 2400000 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 4.1666666666667E-7 × 2.4 kilometers.

Another way is saying that 2.4 kilometers is equal to 1 ÷ 4.1666666666667E-7 millimeters.

Approximate result

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

2.4 km ≅ 2400000 mm

An alternative is also that one millimeter is approximately zero times two point four kilometers.
