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 4210 decimeters into kilometers we have to multiply 4210 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

4210 dm → L_(km)

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

L_(km) = 4210 dm × 0.0001 km

L_(km) = 0.421 km

The final result is:

4210 dm → 0.421 km

We conclude that 4210 decimeters is equivalent to 0.421 kilometers:

4210 decimeters = 0.421 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.375296912114 × 4210 decimeters.

Another way is saying that 4210 decimeters is equal to 1 ÷ 2.375296912114 kilometers.

Approximate result

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

4210 dm ≅ 0.421 km

An alternative is also that one kilometer is approximately two point three seven five times four thousand two hundred ten decimeters.
