Conversion formula
How to convert 7 kilometers to decimeters?

We know (by definition) that: 1 km = 10000 dm.

We can set up a proportion to solve for the number of decimeters.

1 km / 7 km = 10000 dm / x dm

Now, we cross multiply to solve for our unknown x:

x dm = (7 km / 1 km) * 10000 dm → x dm = 70000 dm

Conclusion:

7 km = 70000 dm

Conversion in the opposite direction

The inverse of the conversion factor is that 1 decimeter is equal to 1.42857142857143e-05 times 7 kilometers.

It can also be expressed as: 7 kilometers is equal to 1 / 1.42857142857143e-05 decimeters.

Approximation

An approximate numerical result would be: seven kilometers is about seventy thousand decimeters, or alternatively, a decimeter is about zero times seven kilometers.

Units involved

This is how the units in this conversion are defined:

Kilometers

The kilometre or kilometer (American spelling) is a unit of length in the metric system, equal to one thousand metres (kilo being the SI prefix for 1000). It is now the measurement unit used officially for expressing distances between geographical places on land in most of the world; notable exceptions are the United States and the road network of the United Kingdom where the statute mile is the official unit used.
