## Conversion formula

The conversion factor from decimeters to millimeters is 100, which means that 1 decimeter is equal to 100 millimeters:

1 dm = 100 mm

To convert 70 decimeters into millimeters we have to multiply 70 by the conversion factor in order to get the length amount from decimeters to millimeters. We can also form a simple proportion to calculate the result:

1 dm → 100 mm

70 dm → L_{(mm)}

Solve the above proportion to obtain the length *L* in millimeters:

L_{(mm)} = 70 dm × 100 mm

L_{(mm)} = 7000 mm

The final result is:

70 dm → 7000 mm

We conclude that **70 decimeters is equivalent to 7000 millimeters**:

70 decimeters = 7000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case **1 millimeter is equal to 0.00014285714285714 × 70 decimeters**.

Another way is saying that *70 decimeters is equal to 1 ÷ 0.00014285714285714 millimeters*.

## Approximate result

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

70 dm ≅ 7000 mm

An alternative is also that *one millimeter is approximately zero times seventy decimeters*.
