Conversion formula

The conversion factor from meters to decimeters is 10, which means that 1 meter is equal to 10 decimeters:

1 m = 10 dm

To convert 20 meters into decimeters we have to multiply 20 by the conversion factor in order to get the length amount from meters to decimeters. We can also form a simple proportion to calculate the result:

1 m → 10 dm

20 m → L_(dm)

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

L_(dm) = 20 m × 10 dm

L_(dm) = 200 dm

The final result is:

20 m → 200 dm

We conclude that 20 meters is equivalent to 200 decimeters:

20 meters = 200 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.005 × 20 meters.

Another way is saying that 20 meters is equal to 1 ÷ 0.005 decimeters.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty meters is approximately two hundred decimeters:

20 m ≅ 200 dm

An alternative is also that one decimeter is approximately zero point zero zero five times twenty meters.
