Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 31.7 decimeters into kilometers we have to multiply 31.7 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

31.7 dm → L_(km)

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

L_(km) = 31.7 dm × 0.0001 km

L_(km) = 0.00317 km

The final result is:

31.7 dm → 0.00317 km

We conclude that 31.7 decimeters is equivalent to 0.00317 kilometers:

31.7 decimeters = 0.00317 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 315.45741324921 × 31.7 decimeters.

Another way is saying that 31.7 decimeters is equal to 1 ÷ 315.45741324921 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that thirty-one point seven decimeters is approximately zero point zero zero three kilometers:

31.7 dm ≅ 0.003 km

An alternative is also that one kilometer is approximately three hundred fifteen point four five seven times thirty-one point seven decimeters.
