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 1.4 decimeters into millimeters we have to multiply 1.4 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

1.4 dm → L(mm)

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

L(mm) = 1.4 dm × 100 mm

L(mm) = 140 mm

The final result is:

1.4 dm → 140 mm

We conclude that 1.4 decimeters is equivalent to 140 millimeters:

1.4 decimeters = 140 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.0071428571428571 × 1.4 decimeters.

Another way is saying that 1.4 decimeters is equal to 1 ÷ 0.0071428571428571 millimeters.

Approximate result

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

1.4 dm ≅ 140 mm

An alternative is also that one millimeter is approximately zero point zero zero seven times one point four decimeters.
