Conversion formula

The conversion factor from millimeters to decimeters is 0.01, which means that 1 millimeter is equal to 0.01 decimeters:

1 mm = 0.01 dm

To convert 700 millimeters into decimeters we have to multiply 700 by the conversion factor in order to get the length amount from millimeters to decimeters. We can also form a simple proportion to calculate the result:

1 mm → 0.01 dm

700 mm → L_(dm)

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

L_(dm) = 700 mm × 0.01 dm

L_(dm) = 7 dm

The final result is:

700 mm → 7 dm

We conclude that 700 millimeters is equivalent to 7 decimeters:

700 millimeters = 7 decimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 decimeter is equal to 0.14285714285714 × 700 millimeters.

Another way is saying that 700 millimeters is equal to 1 ÷ 0.14285714285714 decimeters.

Approximate result

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

700 mm ≅ 7 dm

An alternative is also that one decimeter is approximately zero point one four three times seven hundred millimeters.
